Tubes out and testedWiring a bit “freeform”Little radia caps 250V used in the power supply.. HT is only 395V so two 250V caps in series is fineHeater circuit wired up for the Russian 6n2p the customer wanted it rewired for 12AX7 and provided 3 rather nice old Mullard tubesAfter rewiring…12AX7 Tubes in all a glowing…Love this power transformer… so military looking. 2 different heater output one for preamp one for power amp.. about 400V HT when rectfiedOutput transformer is a fair size with tones of bottom end!Checking bias… matching not great between tubes with 20mA on one and 30mA on the other.. a little cold too but the customer liked the sound he was getting so I left them set like that.. no harm in itAll tested and sounding really good!Back together and ready for the customer! Lovely Sovtek MIG50 in to have it’s preamp modified for 12AX7 valves (currently using Russian 6n2p which have different heater pin out to the 12AX7 tubes. Nicely made amp with unusual transformers. Sounded fantastic on the bench when finished. The wiring could be neater though but no issues in functionality.
