Not knowing your budget, or whether you'd prefer a stereo unit or monoblocks, a receiver or pure amps, or even an integrated versus a pure amplifier, I looked on eBay for some stuff that looked interesting and not totally off the charts in terms of money....and I found these. At least it's a place to start..Feel free to ask more questions, and I know the gang here only wants to help...and if something needs fixin...there are plenty of experts here.. GOOD LUCK..I think tubes are way fun, but can get very expensive, and in the end you may love them, or you may go back to solid state, or you may like both...
