I'm having a lot of fun shortwave listening with the reborn British regen. This is the Voice of Vietnam.
I rebuilt the regen using the old Eddystone variable capacitors, the original coil form, the original wooden chassis (now covered with copper flashing) and the original front panel and knobs. But the old triode was replaced by an MPF-102 JFET. And the AF amp tube was replaced by an LM386. Something old, something new... The circuit is the old Armstrong circuit, with a tickler coil and throttle cap. Thanks to Charles Kitchin for all the regen wisdom in his Nov/Dec 1998 QEX article (available on-line).
