･ご注意1: 真空管はピンの十分な清掃と十分な電気的エージングを行ってご使用下さい。旧管種では"必須"です。エージング方法は文献等を適宜ご参照下さい。
･ご注意2: 新品の水銀整流管は、実際の回路でご使用になる前に30分以上のプリヒート/フィラメントエージングが必要です。詳細は真空管マニュアル等をご参照ください｡
･ご注意3: 500Vを越える高圧でご使用予定の送信管は､フィラメントのみで最少6時間(～24時間)、さらに低プレート電圧印加での､数時間オーダーのエージングを事前に行なわれることが必要です｡
･ご注意4: トリタン管では寿命の観点から､フィラメント電圧を規格値の±5%以内の動作条件でご使用ください｡
ご参考 ： Eimac資料から
･ご注意5: 供給電流サージ容量が10A以上に達するような低インピーダンスのフィラメント/ヒータートランス、カーバッテリー、スイッチング電源や安定化電源を用いられます場合､電流制限用のシリーズ抵抗の利用が必要です｡お客様の実際の回路でのご使用にあたられましてのフィラメント/ヒーター断は基本的に保証致しかねます｡（シリーズ抵抗の挿入で電球と同様に長寿命化が期待されます。）古典パワ管のご活用に当たられましては特にご注意が必要です｡(大型の送信管でも「大容量のスイッチング電源」で点灯する場合、数回～数10回の電源ON/OFFで断線することがあります。)
･ご注意6: モールドベースのナス管、ST管、GT管などは製造から数十年を経て、必然的にガラスとベースの接着は製造直後に比較して著しく劣化していると考える必要があります。従いまして、ソケットへの着脱においてはベース部のみを持って抜き差しを行う必要があります。ガラス部分のみを持って着脱した場合、接着がはがれたり、場合によっては致命的にリード線が切れたりすることがあります。とりわけ、モールドベースの古典管をピンロック型の”バヨネットソケット”でご使用になられますと、ガラス把持着脱が必然となり、大きな力が加わり接着はがれが大変生じやすくなります。このような状況に関しましては、当該管の交換に応じることは致しかねます｡
･ご注意7: 長期間ご使用になられておりますアナログテスターでは、確度誤差が10%以上になっている場合があります｡フィラメント電圧のチェックにおかれましては、特にご注意が必要です｡
･ご注意8: ガラスベースやセラミックベースの真空管のソケットとの着脱におきましては、ピンと直交方向に不用意な力を加えますと根元でクラックを生じる事が多くなります。セラミックベースではベースのひび割れや欠けが発生しその後の実装に問題を生じます。ガラスベースでは致命的な真空漏れを生じる事があります。ピンの長手軸方向の力で静かに着脱を行う必要があります。また、ラジオペンチ等でのピンの矯正の折も同じ危険性があります。くれぐれも根元に横方向の力を加えないようにしなければなりません。3C33, 3E29, 832, 5894等の送信管や各種コンパクトロン,マグノーバル管等々のガラス管、あるいは、F2a, F2a11, Z2c, 100TH, 4-125A等のセラミックベースの球では特にご注意ください。
･ご注意9： ヒーターカソード耐圧も製造から数10年を経て、ある程度の劣化を想定する必要があります。規格値に余裕がある設定にしておくこと望まれます。特に直結アンプやカスコードアンプ、差動アンプ、カソードホロワバッファなどを構成する場合、ご注意が必要です。例えば、ミュラード型直結位相反転回路などでは、初段球や位相反転球を交換するたびにチェックが必要です。内部抵抗のばらつきで位相反転段のカソード電位が数10Vオーダーで変化することがあります。このような場合、ヒーターのフローティング回路化が望まれますが、Ehk耐圧規格オーバーの場合は少なくともヒーター回路へのDCバイアス印加が必須です。球交換による音質変化検証実験などの場合は問題が発生しやすくなります。ご購入後のお客様サイドでのH-K絶縁劣化/故障やこれによる部品焼損などに対する保証はできません。

Gpin ** The 12AX7 is a 9-pin noval audio-frequency-dedicated twin triode vacuum tube with the most-highest amplification factor. High applicability, ease of design/use, detailed/high-resolution/deep sounds, high long-term reliability based on very low power consumption/low bulb temperature, and wide variants etc. result in the outstanding popu- larity among wide varieties of twin triodes. The tube was believed to be originally developed in 1946 by RCA (Radio Corporation of America) engineers in Harri- son, New Jersey under developmental number "A-4522". (The oldest RCA-branded one's we have are dated "1950"with white print on glass and also with very-tattered military boxes.) Release date for public sale under the "12AX7" identifier was September 15, 1947. 12AX7 was originally intended as a low-cost amplifier for consumer audio ampli- fier applications. Its wide application use in guitar amplifiers has caused it to be one of the very few small- signal vacuum tubes to continue in production since it was introduced. 12AX7 (1947) has a center tapped filament so it can be used as in 6.3V 300ma, or 12.6V 150mA heater applications. Other tubes with the same base include the 12AU7, 12AT7, and the fairly unknown 12AZ7. Of these the 12AX7 has the highest amplification factor (mu), typically 100. Hundreds of the equivallent's/variations of the 12AX7 have been manufactured all over the world. Variations include the low-noise versions 12AX7A, 12AD7, 6057, 6681, 7025/A, and 7729 (also 12BZ7 (12DF7, 12DM7, 12DT7) is a similar type); European versions B339, B759, ECC83, ECC803, ECC803S, E2164, M8137, CV492, CV4004, CV8156, CV8222, and 6L13;and the lower-mu low-noise versions: 5751 and 6851, intend- ed for avionics equipment. Its popularity has made a complete cataloging of all manufactured variations impossible. In past decades, versions were known to be made in the USA, Canada, virtually every European country, Australia, Japan, India, Argentina, Chile, Brazil, China, USSR, and possibly in other places. Presently the 12AX7 is made in various versions by two factories in Russia, one in China, one in Slovakia, and one in Serbia, for a total annual production figure of 2 million units (estimated). The vast majority are used in new- production guitar amplifiers or for replacement purposes in guitar or audio equipment. .................... One of the obsolete variant 12AD7 were made especially by Sylvania and licenced to NEC Japan, which was used in some old high-end tape-deck's made in Japan. Tung-Sol made 6AX7, and Raytheon produced 2C52 (octal 12AX7) .... which are very minor...Some famous tube-audio enthusiasts say the best-sound 12AX7 is "ECC 803 S" made by Telefunken old plants until early '60s.

Vdrop=10V Ef/If=2.5V/5A (note) RCA-TT3 says: ------- Initial pre-heating : During initial operation, the 866 should be operated for 15 minutes with normal filament voltage and no plate voltage; the 866A, for 30 minutes with normal filament voltage and no plate voltage. This is done to distribute the mercury properly. The procedure need not be repeated unless, during subsequent handling, the mercury is spattered on the filament and plate. Filament Warming up : The filament of the 866 and 866A should be allowed to come up to operating temperature before the plate voltage is applied. For average conditions, the delay should be approximately 30 seconds. ---------- see equivallent types : 2H66/2H66A also see an electrically similar Xenon gas Halfwave Rectifier : 3B28(Ef/If=2.5V/5A, PIV=7kV, Edrop=10V) 0) 866-globe RCA ￥6000 NIB 地図箱(D) 0) 866-globe RCA ￥- WB(T) 1) 866-globe RCA used ￥4500 justLoosePlateCap Strong 2) 866-globe Taylor LikeNew ￥4500 justLoosePlateCap 1) 866-globe Taylor ￥4500 used? 0) 866A RCA ￥3000 NIB(xD) 0) 866A RCA ￥- NOS Bulk 白箱(Q) 2) JAN-CRC 866A RCA ￥4300 NIB RB(sD) 5) 866A RCA ￥4300 NIB RB (hyg1v6nx) (NTB-1) 0) 866A RCA ￥3900 NOS pre-heated 6) 866A GE ￥3900 NIB(hyycng) 1) 866A MarshallElectronics ￥3900 NIB 0) 866A Syl ￥- NIB(sD) 0) 866A Motorola ￥- NIB(D) 3) 866A Amprx ￥3900 NIB(Sn) 0) 866AX Amprx ￥- NIB(vD) 4) 866A Electronic Enterprises ￥3500 NIB pre-heated 2) 866A RCA ￥2900 used 75/40min 5) 866A RCA ￥2200 used 3)元箱(Sn) 2) 866A RCA ￥2200 used GE箱 4) 866A GE ￥2200 used 元箱(Qn) 1) 866A GE ￥2200 used WB 50.5/40min 1) 866A WH ￥2200 used(D) 3) 866A/B SolidState ￥1200 used Silicon Diode w/ OctalBase+TopCap (note) 数10年の保管を経たNOS/NIB水銀整流管は必ず60分以上のフィラメントエージングを行った上で Plate電圧印加を行ってください。866Aでは、1.25V/20分 + 2.5V/40分 推奨。 またお取り扱い･搬送時は垂直保持が必須です。

Among the features are special cathode springs which reduce microphonic response. This characteristic is controlled by a "microphonic stability" test for balance in which the tube is tapped at shock level of 400G to 600G. Other tests which serve to control the characteristics are : 150 hour stabilization, drift, electrical stability, plate current balance, and a maximum grid current limit of 1nA-dc. These test are described under Typical Operation Conditions and Charactereistics. 0) 5755 WE ￥- NOS MB TopGtr(Qn) 6) 5755 WE ￥6700 NIB TopGtr date=6052,6213,6313,6313,6313,6313 12) JW-5755/420A WE ￥6700 NOS ClearTop date=352,(2)352,426,(2)452,452,513,(3)552,552 WB 0) 420A(JW-5755) STC(WE) ￥- NIB ClearTop JW5755のSTC-420A箱入(D) 2) 5755 WE ￥6700 NIB WhiteBox ClearTop date=213,326 2) JW-5755 WE ￥6700 NIB BrownBox TopGtr date=5-59,6-59 4) 5755 WE ￥6700 NOS BrownBox TopGtr date=5939,5939,5939,5952 1) 5755/420A WE ￥6700 NOS 1670/1760/975min ClearTop 0) JW 5755 WE ￥- NOS D/C=726 & 813, ClearTop, gm-matched pair 0) JW 5755 WE ￥- NOS D/C=613 & 713, ClearTop, gm-matched pair 0) JW 5755 WE ￥- like-new ClearTop D/C=813,713,639,652 quad 1) 5755,5755/420A WE ￥4500 NOS? 1730/1350, 1460/1540/975min ClearTop 1) 5755 WE ￥4500 used TopGetter 39.5/38/25min(TV-7) 3) 5755/420A WE ￥4500 used/LikeNew ClearTop 39.5/40.5/25min, 37/38/25min, 35.5/41/25min(TV-7) 2) JW-5755/420A WE ￥4500 used/LikeNew ClearTop D/C=539, 552 gm=1500/1500, 1600/1750 2) 5755,5755/420A WE ￥4500 used ClearTop 0) 5755/420A WE ￥- used?(Aht) 1) 5755 WE ￥4500 usedLikeNew ClearTop 1590/1575/975min date=626 0) 5755 WE ￥- used ClearTop(T) 0) 5755 WE ￥- used TopGtr(Q) 1) 5755 WE ￥4500 used? 1500/1500/975min TopGtr 3) 5755 Tsol ￥3100 NIB ClearTop(T)++ 29) 5755 Ray ￥800 NIB BlkPlate TopGtr(41) 2) JAN-CRP 5755 Ray ￥2100 NIB BlkPlate MB ClearTop date=12-1953, 10-53 1) JAN-JRP 5755 Ray ￥2100 NIB MB BlkPlate ClearTop date=3-40 1) CK 5755 Ray ￥2100 NIB MB BlkPlate ClearTop date=5907 1) 5755 Ray ￥1000 NIB 1) 420A STC(Ray-5755) ￥1500 NOS BlkPlate TopGtr 1) 5755 Canada-GE ￥1000 NIB 1) 5755 NEC ￥1000 used WB

5947 =Temperature limited Diode(TT2)= (EIA/- octal) Bendix said,"This temperature limited diode is designed for use as a stable reference source for voltage regulator appications, or for use in circuits requiring a tube with temperature limited emission characteristics. Temperature limited operation of the tube causes anode current to become a direct function of filament voltage, and thus small changes in applied filament voltage will produce relatively large changes in anode current. The use of a pure tungsten filament permits continuous use of the tube in the temperature limited region without change or damage to the filament during the life of the tube. Close control of critical dimensions and a process- ing schedule designed to eliminate residual gas content, provide a tube with highly stable characteristics held to close tolerance."

VT-2's filaments should be controlled at the current. The nominal current is 1.35 ampares. The voltage varies from 6.5 to 7.5 volts normally among tubes. And the filamentary power varies from 8.8 to 10 watts. As for the #205D, they should be controlled at the voltage which is 4.5V. The current is 1.6 ampare for the #205D, namely, 7.2 watts for filamentary power nominally.
