Hello! Could you please recommend speakers for a 300B tube amplifier? I don’t need disco-level volume. My room is large and irregularly shaped, with the living area connected to a hallway. Sometimes I like to turn the volume up, but I also enjoy listening quietly in the background. What speakers do you use?I’d like a clean, clear sound while still enjoying that characteristic tube warmth.

So, I've built some guitar tube amps in the past and recently a friend donated a Fisher 500-S Stereo receiver. No cabinet. The guts look pristine. Anyway, I've decided to use the iron to build another stereo guitar tube amp based on: A JTM-45 and, a Train Wreck Express. The last one I built and use is based on a Sunn Sceptre power amp design. Which initially Sunn sourced the power amps from Dynaco; as the story goes. The Sceptre was a mono amp so I simply built two channels using a power transformer from an 100 watt amp and Train Wreck output transformers. I use it with an amp modeler and effects unit. Sounds great. The reason I joined the forum is due to my lack of knowledge on how best to integrate the two amps, as well, the tweaks needed to integrate a selected power amp section and…

Good afternoon, everyone.

I’m currently looking for a good output transformer for an amplifier project and would appreciate some expert advice.

Specifically, I’d like to know:

• What key specifications or features should I pay attention to when choosing an output transformer in the budget/mid-range sector?

• Which manufacturers offer the best value for money in this price range?

• Are there any Chinese brands worth considering that perform well without breaking the bank?

Did the ultimate 2a3 deluxe amp with the ISO FC-30 transformer ever get built? Did anybody build this amp? The transformer shoot-out showed such good performance from the FC-30 that it makes me curious how such an amp would sound. I’m thinking about building one but I’d love to hear what someone else has to say of the sound produced by this ultimate build. I’m referring to a version with the silver wires, Horizon or EML tubes, RCA drivers, and maybe the alternate rectifier tube. If anyone knows anything concerning the performance of the FC-30 output transformers I’d like to hear what you have to say.

Stephe, I know you’re busy with the listening room and other projects but if you have any other suggestions for substitutions or tweaks from the standard Skunkie Designs 2a3 to the top shelf deluxe 2a3 I would love to get your thoughts. No rush,…
