Yes, you are probably correct but I'm too old to be vain.
"The Old Trout" is a quaint English unflattering term of endearment sometimes used by middle aged men when referring to their wives. I live in a village called Charlton MacKrell [yes that is the correct spelling not mackerel] My old boss used to refer to me jokingly as” the old trout from Mackrell” - a silly play on words but makes an amusing moniker.

Back to valves!

Angela,

Good for You!!

(Guys, here comes trouble. Seeing the very professional layout and probably likewise circuit diagram ....)

From another (old) professional engineer: Welcome!

?????
Where did she do that? Every living being, also fish, can become 'old' in their turns without being dead - also you, me.... (Neither offence on this side, nor understanding!)

Totally off-topic, but reminds me of trout's fellow Englishman, George Bernard Shaw:

In his day he had to attend quite a few 'socials' - and hated all of them. Said about one particular such, as GBS entered the 'presence', cigar steaming as usual. Up sidled a bedraped full-figured female socialite, reeking of scent:

"Sir! You SMELL!"

GBS: "Correction Madame! YOU smell; I stink!"

But light relief; Back (with an effort) from the olfactory to the otic.

I'm currently building a phono pre-amp to accompany it.
Ma'am, with permission... you are the kind of girl who warms my heart!

what is 'girly' about it?

"Girls" are more often think visually than "boys". Did you notice?

Default Surplus PCL82 PP Stereo

I finished building a PCL82 Push Pull stereo amp using the schematic from post 713745. The only difference is that I had to change the cathode resistors as the one on the schematic was exceeding the plate dissipation of the tube. I ended up putting a 1K ohm resistor, drawing an quiescent current of 25ma. Since the tubes were surplus and unmatched, one of the tubes had a combination of a 560ohm and a 1K 15 turn trimmer from Radioshack. This way I was able to match the currents. Other than that the amp is very silent and sounds very nice. Need to build some high sensitivity speakers next.

The amp is build will almost all surplus parts.

output transformers are 7010 line matching transformers, 8K to 8 ohms.
Power transformer is a triad 35va isolation transformer with a voltage double power supply.
The heater is a 16v @ 1.6amps.
The case is a LACIE usb drive case.
