RE: WECo 91A/B--Long, but hopefully informative

Thank you for taking time time to write such a detailed response, it actually is a big help, and it settles some points too.

1. Input tubes will be metal 6J7. 6J7 has lower distortion than 6SJ7, and it avoids the need for a weird tube socket. Metal version because of shielding.

2. The tone shaping network will require some playing with to get right.

3. I will use PSUD-II to model various power supply configurations, but I plan on staying with multiple series connected electrolytics, like western electric did... The challenge will be specifying an appropriate choke.

4. Output tx puts me at a loss. You seem to have tried them all, basically I would say I will buy it on spec ... Best compromise between distortion at 20 hz, -3db high frequency limit, and price. Not everyone has this info though so it may take some gambling to get it right.

5 I plan to start with as close as possible circuit to original and then optimize it, so wiide bandwidth is absolutely necessary from output tx
