Hi Myles,
I am new to the forum but have been reading your posts for a while and find them very interesting and helpful.
I have a question regarding a matched phase inverter valve. My amp is a 65 Twin Reverb re-issue project. It has a Hoffman AB763 board kit, Mercury Magnetics transformers, Torres Engineering beefed up mod kit and Tone Tubby speakers etc.
I am about to replace 6L6's with Tung-Sol 5881 (#5) valves.
What matched phase inverter valve would you recommend for this amp?
Thanks, any advice is appreciated.
Powerage
