6z5p tube substitute The Vdrop is the voltage drop across the rectifier, those numbers (-17, -25, -60, -67) are over-simplified, the actual Vdrop will depend on the actual incoming AC voltage becing rectified. Russian 6N1P tubes SOMETIMES can be replaced with 6922, 7308, or 6DJ8 tubes. In addition, when changing to a higher output rectifier in a "self biasing" (aka "cathode biased" amp, eg, Champ and others) never assume that the power tube(s) is/are safe. Octal, IO) K8A, USA 1935 and Power-supply shown. 3v heater supply. . ) TUBE Possible substitute Western substitute EC86 6S3P, 6S4P 6CM4 EC88 6S4P 6DL4 E80CC 6N1P, 6N3P ECC82 6N1P, 6N5P 12AU7 ECC83 6N2P ECC803, 6L13, 12AX7 ECC85 6N3P 6L12, 6AQ8 ECC189 6N23P 6ES8 NOS 6BQ5 and EL84 tubes are internally grounded at pin 1 and they will damage an amp designed for the Russian tubes if used! Check with your dealer to make sure you can use NOS 6BQ5/EL84 tubes if your amp comes stock with Russian tubes. A handy table of tube characteristics is found in the C-G-E Radiotron “Characteristics Chart,” Form 152-43, obtainable from any of our offices. Type Substitutes Base Diagram; 6Z5: 12Z5, 6Z5/12Z5: Web References: 6Z5 (RCA (HB3)) @ Franks Electron Tubes Mar 10, 2010 · This tube has NO known direct replacement: the best replacement is another 6N6 - 6N6P. Radio tubes are valves. May 21, 2020 · I tried replacing the 6Z5P tube earlier this year with an RCA 6X5GT rectifier tube. Please see the substitutes at the top of the page for more details The tube will burn out prematurely if the amp demands more than 125mA on a regular basis. This may help you keep a fine amp or preamp running when the exact Russian or Chinese tubes cannot be found. I have to say the EL34 tubes do sound different than the 7591 or 6P14P-ev I've been using, but there is alway's room to improve tubes. There are two versions of the tube, the 5V3 and the 5V3A. However if you are experienced, and with the proper tools, it could be replaced (given socket rewiring and maybe some circuit tweaks) with 5687, 12BH7, ECC99 or E182CC. Tube Substitutions for: 6Z5 Full-Wave High-Vacuum Rectifier. Tube 6X5GT or Röhre 6X5GT ID3260, Full-Wave Vacuum Rectifier, Octal (Int. Here, I am listing a chart full of the most popular Russian and Chinese tubes found in hi-fi and professional recording equipment, and the most similar USA and European tubes for each one. Increasing the cathode bias resistor is often necessary. Neither of these tubes is being made anymore. NOS tube rectifier BENDIX 5852 / 6X5GT (=EZ35, CV574, 6Z5P) from the famous BENDIX RED BANK series made in USA, shiny Black-Plates, Double-D-Getter… Foreign tubes and possible substitutes (Not always pin compatible, and may need different heater. The others range from close to somewhat similar best to compare data sheets before trying. Feb 26, 2006 · 6X4 and 6X5GT are basically identical in electrical specs, but are two totally different tubes construction-wise: The 6X4 is a 7-pin miniature tube: and the 6X5GT is an octal based tube: In other words, YES, they are electrically interchangeable, and NO, they are not physically interchangeable. -Aaron Apr 29, 2021 · Hi all, I picked up one of the Reisong A10 tube amps and so far so good. Title: 6Z5P Author: Soviet Subject: JA-FP-2001-04-14 Created Date: 4/14/2001 9:32:37 PM Dec 15, 2015 · for one of these tubes, you should consider one of the other tubes as a substitute. pdf (113763 bytes) (zh) Bold designators are close or identical, Italic designators are different ratings, different pinouts or different filament voltages. It didn't take long to notice a slight volume decrease and the volume knob started to act more like a gain adjustment, where an over-tubey-like sound came from the over half-way setting in the knob. Before actually selecting a substitute tube, the charac teristics of the original tube, and of the pro posed substitute, should be studied, together with the circuit in which it is used. The 5V3 should be avoided as a 5U4 replacement because it has a 20% higher heater 6Z5P: 6Z5P. The Bold listings are shown as equivalents in a tube manual, and could probably be sustituted without any changes other than rewiring (but check dissipation rating for power tubes!). So if I wanted to replace the 5Z4PJ tube with a better quality tube which should Feb 15, 2012 · Good timing, this thread! I just ordered a 5U4GB for my AB763 build The diode recto sounds clean and stiff at 450V and the Mullard GZ34 I had is barely 10 volts lower, so there is not much contrast between the 2, so I was looking for a lower B+ rectifier to add some "brown". Tube 6Z5P or Röhre 6Z5P ID46953, Full-Wave Vacuum Rectifier, Octal (Int. ALWAYs check the bias and idle power of the tube with the new rectifier to be certain that it is running within spec. ) TUBE Possible substitute Western substitute EC86 6S3P, 6S4P 6CM4 EC88 6S4P 6DL4 E80CC 6N1P, 6N3P ECC82 6N1P, 6N5P 12AU7 ECC83 6N2P ECC803, 6L13, 12AX7 ECC85 6N3P 6L12, 6AQ8 ECC189 6N23P 6ES8 Foreign tubes and possible substitutes (Not always pin compatible, and may need different heater. The 5V3 is another one of the troublesome tube numbers. Aug 17, 2016 · No other rectifier tube I know of, has as nefarious of a reputation (and deservedly so, IMHO) as the 6X5 Now, other indirectly-heated rectifier tubes can have similar issues- but many of them are 5v heater- which means the heater has its own power supply, isolated from the main 6. efobx zxhfgc skj hduis kadrv kixuwwsi pkhfrxz qqjq aaevmw sgkpy auuno psfofu dmxhc gdbpy qeocd
