Default GU-50 100W output and power transformers

I am going to order custom transformers for P-P GU-50 amps,

10K CT primary, 4-8-16 Ohm secondary, 100W power 30Hz-20KHz.

Also, appropriate power transformers will be ordered.

I hope to get decent output trannies under $70 (plus shipment).

Power transformers I believe will be under $40

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 am lucky I did not rush to order them: actually 5K CT is needed for 100W P-P amp using GU-50 tubes.
