Tube amplifier build

I've had a couple Triad HSM-94 output transformers sitting around for quite some time and would like to build a couple DIY mono amplifiers. Not a lot of info on the internet about the HSM-94's but do know they work well with 6550, 6L6GC or EL34 tubes. Info I've read says they are good for about 55 watts.

Anyone know of a good circuit to use with these triads?

If good for 55 watts a KT-88 or 6550 amp would be nice. A pair of KT-88's or 6550's should be good for a 60 to 65wpc push pull amp. You could run the tubes at a little lower voltage to accommodate either of those tubes used with those ourput transformers. I have a pair of parallel push pull mono blocks with KT-88's. I like the low end the KT-88's produce. Its well controled too. It might be easier to build a 35wpc EL34 amp though. You ould have enough headroom with those OPT's. You could even build a Dynaco ST-70 clone that uses EL34's if those OPT's have a UL tap. I built a ST-70 using Tubes4hifi's driver board I really like.

Citation V, Williamson or PP 300b would all be reasonable choices.
A PP 300B amp could sound very nice. I have a 300B SET amp, but I would like to hear a 300B PP amp sometime. I'm guessing it would sound at leased as good as a single ended 300B amp.
