I hope to get decent output trannies under $70 (plus shipment).
Power transformers I believe will be under $40

What is the rate of that THD to USD?
World rates: http://www.xe.com/
P-545 (80W-PP)=12 000 Baht => U.S. $ 373 (pair)
not cheap, but they compare themselves among the best.

I've found a supplier. They want $70/each if I buy 50 of them. Shipping will cost another $560 to my address in California, so I'll have them in my garage for 81 + VAT.
Are you in for $180/pair plus actual shipment costs?
For now:
Cobra2: 2
agent.5 :2
Wavebourn: 46
Waiting one week then ordering them next Monday...

agent.5 said:Yes. Please also allow an ordering option for mono blocks (2 power transformers). What is the spec for the power transformer?
120V primary, 285+285V 0.6A anode, 12.6V x 2 3A filament, 100V 0.1A bias
(GU-50 filaments will run from 12'6V AC, the rest from 12.6DC regulated)
I did not find a supplier for them yet, I want to order toroids.
$ 180/pair is not to bad. But are they good? I would rather spend twice as much, if I was sure they did not end up as very expensive doorstops...

Did you plan to use any chokes?
Arne K
Do you mean 2 power transformers?
No, I do not need a choke, I will use IRF730 to regulate screen grid and preamp power.
Looks like there will be kits available including PCBs...
