Very nice! I like the bypass idea for "bleeps", etc.

I don't understand why everyone jumps in to answer this question, and never
answers any of mine.

I think it's a conspiracy to keep me from challenging your careers and
stealing work from you.

"Audio Transformers CAN be Good"

and

"Output Transformer Design"

I'll post them over on ABSE.

If you can't get that group, post an email address here and I'll email them
to you.

Has anyone had experience with similar sources, or know where they are sold?

If you want to make 200W of power with tubes now,
and you wish to use triodes, then 4 x 845 is a nice way to do it
and you'd need a similar sized chassis for at least the power amp as in
1940 if you like to to things right.

I recently built a pair of class A 55W SET amps using 2 x 845 per amp,
and I used all the weight of iron they used in 1940 and perhaps more per
watt, being SE.

2 x 845 are also capable of giving 55W class A in PP,
with Pda at idle = 78W per 845, same as with SE use.
If one lowered the Pda to about 60W each tube, then you'd get about 40W
max of class A,
but maybe 100W in class AB1.

But today we'd use silicon rectifiers and voltage doublers to make the
B+
required for such amps, so the PSU chassis would be a lot smaller and
simpler than in 1940.
And the chokes for filters would now be smaller because we have reliable
electrolytic capacitors of enormous
capacitance values and small size, much better than the huge paper in
oil types they used.

The Dyna output transformers are not optimal and shouldn't be messed with
by scratchbuilders. If you value your own time, ante up and buy a pair of
new transformers. Several new good choices are available, some as cheap as
$75 or so.

I bought a 150 lb. box of transformers at a hamfest a couple months ago
for $25. I pulled out a couple of NIB Stancors powers and a WE 111 and
eBayed them, and sent everything else to scrap. Some of them probably were
perfectly good. We came out ahead on the copper alone, I sold all the lams
along with a few junk engine parts to the car crushers'.

They will be smelted and the silicon will come out of the iron. New steel
will be made from them.

Buy some new iron, you cheapasses, and keep America working.
