Craig Sawyers Posted June 28, 2019 Report Posted June 28, 2019 (edited) Are those transmitter tubes in the Moth amps? Edited June 28, 2019 by Craig Sawyers
Dusty Chalk Posted June 29, 2019 Report Posted June 29, 2019 Radar tubes And it’s not even an amp, it’s a night light. (Actually it’s more of a conversation piece, and that conversation usually has the phrase, “good lord!” declared at some point.)

Craig Sawyers Posted June 29, 2019 Report Posted June 29, 2019 That is a totally insane tube! https://frank.pocnet.net/sheets/140/3/304TL.pdf . 3
Torpedo Posted July 7, 2019 Report Posted July 7, 2019 I have no idea how the Phonitor sounds and if it's worth the price of admission, but it's one of the coolest with all the pots and the VU meters.
RudeWolf Posted July 7, 2019 Report Posted July 7, 2019 Supposedly starting from Phonitor 2 they're really good. XE has the same amp topology, but with a proper balanced output. The inner signal paths are SE, as doing a balanced X-feed matrix would cost a fortune. 1

skullguise Posted July 24, 2019 Report Posted July 24, 2019 I remember that, and the battery-powered T-Amp to drive them! used to own that pairing myself.....
Pars Posted July 24, 2019 Report Posted July 24, 2019 (edited) You know it's serious with cable lifters... Edited July 24, 2019 by Pars
skullguise Posted July 25, 2019 Report Posted July 25, 2019 ^^^ Those Dali's should be in Speaker Porn....I've liked some of the sound I've heard from that small dome mid and ribbon tweeter of theirs....
