They were designed by Bruce Moore (Bruce Moore Audio Designs) and Scott Frankland (Wavestream Kinetics). They use top quality parts and are hand built in the USA, using the point to point wiring method. They have unregulated power supplies (no current limiting) and run in class A up to 40 watts output, and class AB1 above that. They can also use KT88s, KT90s, and KT99s. The amps are rated at 75 watts per amp into 4,8, or 16 ohm loads. They use some of the biggest transformers of any amps in this power range and are extremely wide bandwidth (16-80khz). They sound lush and detailed but with plenty of sparkle in the highs and lots of authority and control in the bass. These are classic designs of top quality and are quite rare. The amps also have AC balance pots to fine tune them. please note the amps are 118V . stepdown transformer can be arranged Payment Method: Pickup - Cash, Paypal + fees , bank transfer Pictures: Edited May 20, 2017 by anthony vinyl 1
