You can go with EL84's if your speakers are this sensitive. A pair per channel will probably sound better than four if you don't need the extra power. Sorry, not sure who to suggest to build them for you. Restoring something vintage to the max may give you better value than custom newly built. You could splurge on the best tubes and you would have fine old output transformers on board. The Fisher 30A mono's come to mind. Or even the 80's with 6L6 tubes.
Custom Builder For P/P Power Pentode Amplifier
Hello All,
This is not a request to debate the merits of SET vs Power Pentode (push/pull) amplification. Instead, it is a request to the community for recommendations for any custom builders you know of (e.g., Niteshade, Trafomatic) who are quite good at this craft of building a p/p power pentode amplifier. These will be integrated with speakers that are :
A 2-box ( per channel ) loudspeaker, where the full-range module (7” driver) is physically separated from the bass module. The latter has three 6.5” drivers into a 4 ‘ long horn. Bass module is driven by its own FET custom amplifier. Overall sensitivity 102 db/w/m. Nominal impedance 8 ohms and frequency response of 18Hz to 20Khz.
Again, this is not a request for arguments pro and con. I am beyond this now. It is a search for recommendations for the very best builders for this kind of amp. Many of the builders that are ofter shared are really into SET as opposed to what I am looking for.
Thanks for your help.
