London Power's "PA"-series Tube Power Amplifier Kits
Have you tried one of these? Post your questions or comments!

These octal, push-pull power amp kits use London Power's full-audio-bandwidth OT-10, OT-25 or OT-50 toroidal output transformers. Performance is so good they can be used for hi-fi. The power amp can be used with any of the common octal-based output tubes that use the standard pin-out. Tubes can be mixed as well!

Switching between fixed-bias and cathode-bias can be "global" (both tubes) or independent.

Please remember these three principles: respect, sharing, community.
