June 28, 20197 yr Are those transmitter tubes in the Moth amps? Edited June 28, 20197 yr by Craig Sawyers
June 29, 20197 yr 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.)
June 29, 20197 yr No, Dusty, those are not the Moth night lights, those are Moth M-304-TL power amplifiers. Moth Audio web site (May 19, 2010): 35 watt single-ended class A1 no feedback interstage transformer coupled monaural amplifier. Specifications: Topology: One triode for voltage gain, transformer coupled to the output power triode. Only thermionic devices and magnetic circuits are used. No coupling capacitors and no feedback. The output power triode never leaves class A, operation and is used at half its rated plate dissipation for longer life. Tubes: Four 6D22S rectifier "Svetlana" (Russian) One 5Y3 rectifier "Sovtek" (Russian) One 5842Q voltage gain & driver "Sylvania" (USA) One 304TL output "Imac" (USA) Wiring: Hand wired point to point for all circuits. Cardas solder user throughout. Capacitors: Polypropylene in soybean oil for power supply circuits. Output Transformers: Custom manufactured for Moth Audio Corporation. User selectable: 2,4,8, & 16 Ohms. Connectors: Cardas rhodium plated RCA for unbalanced input, Neutrik gold plated XLR for balanced input. Silver-plated speaker connectors. Chassis: Zinc plated 18-gauge, cold rolled steel with a heavy wrinkle black powder coating. Polished and black anodized 3/16" thick aluminum top and bottom plates. Brass plaques are custom etched and filled. Indicator pins are 24K gold plated. Glass Bell Jars: .25" thick hand blown Pyrex with acid etched logo. Power Output: 45 watts, 5% THD @ 1kHz. Total Harmonic Distortion: Less than 1% 40 - 20 kHz @ 35watts. Power Supply: Low-flux leakage design using toroidal power transformers as well as toroidal inductors. Frequency Response: (-3dB Points) 10Hz - 40 kHz . Input Sensitivity: 1.5V for 35 watts out. Input Impedance: 100k ohms unbalanced. 600 ohms balanced. Power Requirements: 105 - 125 VAC 60Hz (210 - 250 VAC 50Hz.) 400 Watts. Dimensions: 20"H x 15.75" W x 23" L Weight: 75 Lbs. Warranty: All components carry a 3-year parts and labor warranty. Tubes carry the manufacturers' warranties.
July 7, 20196 yr 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.
July 7, 20196 yr 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.

July 24, 20196 yr I remember that, and the battery-powered T-Amp to drive them! used to own that pairing myself.....
July 25, 20196 yr ^^^ 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....
