Model: 8b clone RMS Wattage: 35/70 Channels: 2 Channel The output transformers are vintage Dynaco ST-70. The 6BH6 preamp tubes are NOS Jan/GE. The 6CG7 phase splitters are NOS Sylvania. The EL34 power tubes are a NEW matched quad of JJ's. The rest of the amp is NEW. The chassis is 1/8" steel and is custom. Hardware is all stainless steel. Wiring is all silver plated pure copper Litz wire with Teflon insulation. The circuit is based on the Marantz 8b With improvements. The power supply has twice the filtration/capacity of the 8b. It has three transformers. One for the high voltage and heaters. One for the bias supply. And one for a regulated DC supply for the 6BH6 heaters. The amp uses a TC5 choke from VAC made for the 8b reissues. The high voltage has thermistors to delay high voltage till after the bias comes up to save the output tubes. All resistors are 1% metal film. Tube sockets are ceramic. Signal capacitors are Solen polypropylene. With the Dynaco transformers the feedback circuit had to be re-tuned. The amp has gold plated RCA jacks and banana plug/binding posts for the speakers. Get Questions? Email Us! ============ hechao1958@hotmail.com
