Hi all, I am looking for some advice as to where best to source three (including a matched pair) of 12ax7 valves for my minimax phono preamp. It also takes a 6x4 rectifier but not sure if I need /want to replace this. I have the stock valves that came with the amp from Eastern Electric and I’ve had it for 10 years now, just upgrading my main amp and want to try something better that will do the rest of my system justice. (Michell Gorbe/SME m2/9 / Lyra/ Sugden Masterclass/ Goodman Magnum K’s.) I’m bit wary of eBay so would really appreciate some guidance for reputable resellers. -
Further information: Up for sale is Yaqin MC 100B Integrated tube/Valve amplifier in excellent working condition along with $300 worth of upgrade. This is a true duel mono block amp having 2 seperate power transformer for each channel (hence there are 4 transformer rather than 3 which are on most of tube amps). Pre-amp tubes have been upgraded to Electro Harmonix 12AX7 Coupling Capacitors have been replaced with Mundorf MCap Supreme 1uf. Capacitors are so big that they had to be mounted on chassis rather than the PCB (check photos). These 2 upgrade make this amp comparable to high end
