Antique Sound Labs AQ-1006(845)DT mono blocks, one 845 power tube per amp = 22 Watts/channel with 4, 8, or 16 Ohm connectors. Purchased directly from Scott Frankland (MFA and Wavestream), who had updated amps to increase reliability and improve sonic performance, in December 2014. Problem-free operation and excellent sonics with my Green Mountain Eos speakers.
Tube complement per amplifier: Three vintage 6SN7's: input Sylvania brown base, driver Raytheon, regulator RCA red base; Genelex KT77 pass tube (purchased from Jim McShane); Valve Art 845.
Have decided to keep 'em!
Thanks! and happy listening.
