2022年8月1日 · For the 35L6 see pg. 343. So if your radio uses rectified 117V AC line voltage for the plate supply, 2.5k is going to work better. If there is a 230V line, a power transformer, or a voltage doubler involved, with around 200V B+ for the stage, about 5k is what you would prefer. Virtually all radios ever made using the 35L6 used cathode bias. In ...

2015年4月18日 · I was pulling out the tubes on the radio I'm working on, and I noticed that the 35L6 tube is completely opaque black. This is a glass tube. I have seen a lot…

2025年1月9日 · Tube lineup: 12SA7, 12K7, 12SQ7, 35L6, 12SQ7, 35L6, 35Z6. Late 30s, maybe? Steel needle phonograph. BTW, I can't seem to get to the Mallory-Yaxley web site. Every time I type the web address into my google browser, it inserts the "S" behind the HTTP and says the site is not found. Anyone have any help for me there? Best Mike

2011年5月23日 · The General Electric 321 is a six tube radio, originally made with four 12-volt tubes and two 35-volt ones in series, giving a total drop of 118 volts. With a 50L6 in place of the 35L6, total drop increases to 133 volts. Chances are your line voltage is not that high, and the tubes are running under their nominal ratings.

2025年2月16日 · Unless the transformer has been replaced with one without the tap you should find three cloth covered wires coming out of it. ( one may be underneath) There's nothing to do with any of the capacitors that will cause no voltage on pin three of the 35L6. Either the transformer is bad, or the "red" wire is disconnected.

2014年4月11日 · The lower heater voltage applies to the use of two 50L6 tubes, not two 35L6. The string is 50 + 50 + 12 + 12 + 12 = 136. Assuming 120 VAC line in, that's 88% , or roughly equivalent to running an AA5 on 105VAC instead of 120. No problems there. I think 35Z5 was referring only to the heater voltages, not to the 35L6 amplifier characteristics. Rob

2002年1月7日 · The 50L6 seems to be written so that pins 3 and 5 are grid connections and there is no Plate connection. I'm thinking this has to be wrong. 35L6 shows pin 3 as a plate connection and 5 as a grid connection which is correct. That being said, I am thinking I should be able to set the 50L6 as a 35L6 and test it. <P>The Voltage setting is the Bias ...

2007年3月5日 · Hi all, Went to work on a Philco 46-1203 radio/phono today. Tube line-up was supposed to be: 7C7, 7A8, 7B7, 7C6, 35L6 and 50Y6. That's according to SAM's sch…

2015年8月9日 · For the 35L6 tube, the absolute max audio output power at the speaker is around 3 to 3.5 watts. Ideally, you should choose a speaker that would accommodate this peak power. Practically speaking, no one is going to operate their radio at full volume (and horrible distortion!) for extended periods, so you can get by with a smaller speaker power ...
