Interesting. This device needs 12 volts but has a tube which looks like an old 807 (but I think the 807 had 5 pins, and this has what looks like 7 pins so it may be a 1625). There is no power componentry for such a tube (it needs around 400 volts for the plate) so that's likely decorative, or maybe some of the hardware is not shown? The detail on the photo is not good enough for me to tell if the plate cap lead actually goes anywhere. Or maybe the tube envelope was opened up and a small transistor preamp was mounted inside the tube envelope. That would be hard to do. Or, maybe in the tube base. That might be doable. Then that makes it just misleading. The tickler coil appears fixed-wound on the coil form. A regen should have a way to adjust the tickler coupling. A mystery to me. - Bob _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
