Feb 27, 2019 · Unless your 6Y6's screen is idling at 11.4mA, you don't need to be confined to 135v. To verify, measure resistance of the 8.2kΩ (amp off), then measure d.c. volts dropped …

Feb 26, 2018 · Substituting a 6V6 for a 6Y6 seems entirely practical and at the same time gets rid of a bunch of filament supply drain (1.25 A for a 6Y6 versus .45 A for a 6V6). It certainly won't …

Feb 18, 2020 · trimmed back on 6Y6 g2 supply - was adding a fizz to high notes when full up. i can run the master full up with that annoying artifact. added some more filters to help stabilize …

Dec 2, 2008 · Although they can be interchanged watch for voltage and current. Using a 6Y6, as example, filament and plate current will be much higher. Max voltage ratings are much less for …

Aug 12, 2010 · A 6V6 will work for 6Y6 but output will be reduced. A better sub for 6Y6 would be 6W6. 6Y6 was made to operate with low voltage, high current. 6W6 operates with similar …

May 11, 2021 · I was able to hold my hand on it after a full hour of operation, but it seemed a little warmer than most sets in the collection. I was wondering if the 6Y6-G tubes in my set could be …

Jan 22, 2025 · The 6Y6 in this "Cathode modulator" simply takes the place of that resistor to ground, as shown in "B" below. The modulator assembly gets its B+ from the cathode of the …

The only thing I noticed that didn't seem right was the 6Y6 control grid voltage; like the previous amp, it still isn't negative, but swings around from maybe 0V to 0.015V. The datasheet …

Jul 17, 2010 · 6Y6 Application Data Class Va Vg2 Vg1 Ia Ig2 Ra S Zout Pout A S/E 200 135 -14.0 61 2.2 18,300 7.1 2,600 6.0W Z was 2.5 to 4.5 k (lower voltage with lower Z)

A 6Y6 tube running in Ultralinear with 135 volts on plate & screen would probably only output a watt or two of audio. As soon as you try to play it loud, it will sound bad, defeating the whole …
