Nice video Steady 330 - but these stock tubes are not what this amp needs to shine!!!!
If you put a quad GEC KT88 Triple Getter Black Plates (NOS) a pair of Telefunken ECC83 Smooth Plates and ECC82 Smooth Plates and a pair of RCA 12BH7 Black Long Plates on that machine, than I would say, it gives the best vintage MAC 275 a run......and itīs not even close.....
The miracle sits in those large Tamura transformers - and the layout is closer to an old vintage MC 275 - Miura San decided to use, as it is in those vintage MACīs - the 12BH7 as a driver for the KT88 - all modern MAC MC 275 use 12AT7 for that job.
Thankīs for the nice video....
