I purchased the MC-13s as a back up to my old vintage H.H. Scott 208 power amp which uses 7591 tubes. I got it from a U.S. seller for a decent price i guess$550. I am very happy with it and im glad it's bias adjustment is done by the user instead of auto-bias. I opened it the first day i got it to inspect the build quality and was satisfied even though its not Point to Point wiring. But i want to do some tube rolling, preamp tubes that roll off the highs a bit, so if anyone know of 12ax7 or 12au7 that does this, please let me know, i don't really care for bright sounding amps like many of today s tube amps, they are a bit too detailed, that's what i like about the Scott 208 7591 tubes. I also added (4) 0-1volt meters so i can see what the voltage is in real time, its a simple procedure. I also added Temperature gauges on top of the meters that displays the temperature of the Output Transformers, i may do the same for the Power Transformer as well. It is now encased with thin plexiglass with 40mm exhaust fans to suck out the heat.
