They were mostly rectifiers but there were three Triodes
1-PX25 and 2-STC 4275a
The 4275a or WE 275a are as rare as hens teeth so it was strange
to see a pair sold in the listing above the Box of valves, they sold for
£650.
They are a sort of WE 2A3, sorted the fil volts and they biased up at
288v and -56 and they sound real smooth
