sir Tony,
Thank you sir, i'll stick to the plate loaded, it will be a waste of effort, time & money to build just to dismantle it again just because because i'm not happy the way it performs, and I hope this educate not only me who is a newbie in tubes but others like me who read this post, very educative, my hat's off to you sir Tony!!!
One more sir,...after you post about rectifiers, I replaced the 5Y3GT in my amp with pea sized VO6C rectifiers rated at 1 amp each( i used 4, two per tap in full wave)and here are the positive results:
1. no voltage drop- with tube rect, at power on 286 volts, settled at 236 volts after warming up.
with silicon rect. steady at 336 volts +/- 2 volts variation which is negligible.
2.sonic qualities/ transparency- I was amazed as the sound became much more transparent, if I may
desribe, it is "clear as a crystal", as a bonus the bass was more tighter.
Even at low levels, it is well defined.
Now for the negative:
1. What was dead silent before, now there is hum, my ears about 1-2 inch from the cone; i listened last night at very low levels, at listening position, the good news is hum is inaudible.
2. I usually turn off the lights when listening at night, the sight of glowing tubes is kind of nostalgic, however since replacement of rectifiers, last night i noticed the slightly dull orange(not really glowing) in the plates of output tubes, a sign maybe they are driven to their limits?
or is it just normal considering they are operated purely Class A?

The OPT's of sir edrel remain at normal operating temperature, even if operating for more than two hrs.
It is just perfect
I wonder what can i do with those spare 5Y3GT & 5U4GB
A lot of "tuberos" still prefer tube rectification for a number of reasons, but for me my next project will be silicon rectified. Anyone out there want to swap these two for 6pcs OCTAL Sockets ?
