6550b amplifier schematic

[markbomeisl]

Hello
I recently acquired two Hammond 1650NA (60w 4300Ohm)output transformers, a Hammond 278CX power transformer (800v ct 535ma)
and Four Bugera 6550B tubes in a trade.
All new.
I want to build a push pull stereo amp.
Can anyone point me to a good schematic to start from.
Thanks

Please use the forum search function, there are hundreds of threads on the 6550/KT88 amplifiers.

Thanks I will search.
If anyone can recommend a good design I would be appreciative.

I could give you two, but I am away from home and have only this iPad with me.
If I can remember, I'll be back.
Oh heck, you have them here:

Thank You!
Have You built either of them?

An externally hosted image should be here but it was not working when we last tested it.

This one worked pretty good. I would do the power supply completely different nowadays, but oh well.

No, but both are from very good engineers. One of them is designed by Erik Andersson, the guy behind Audion.
