this is my 12W6 pp amp, the output tubes are a dollar each at Rogalskie's in Florida,
topology is like a mulard 5-20, but uses a 12at7 input and 5965 LTP's..
operated as a beam pentode with G2 regulation using an 0A2 gas regulator tube..
more than generous filtering in the power supply....

available at Remington's place by this coming weekend....

you can have a chance to listen to how a beam pentode sounds like,
as compared to ultra-linear amps using the traditional power tubes...

TV tubes are not suitable for ultra linear because of their low screen voltage specs,
but these tubes are high transconductance and therefore linear even at low
plate voltages....

yes sir fresh from master tonyT's kitchen umuusuk-usok pa he he! initial impression.....matutuwa ang mga basshead na mahilig sa tubo at grabe ang gain he he...

tony · « **Reply #149 on:** Mar 20, 2014 at 09:43 AM »

the amp is now with me to fix some issues...

gain is way too high so took care of that,
the 0A2 regulator blinks, a sign that is it is
running out of current on music peaks,
took care of that too..
noticed that one sylvania 12W6 red plates at 15 volts bias,
so i replaced the entire set with RCA 12EN6's,
no more red plates....

the current setup now is, 12EN6 output tubes, 5814 long tail pair phase inverter,
and 12AV7 as input tube....although the JJ 12at7 and siblings had more gain and decent sound,
i found out that 12AV7 is even better in that spot, perhaps becuase the 12AV7 has lower rp than the
12at7.....so i am working the amp real hard now.....
