Vintage amp restoration and Beyond

[karpathion]

Speaking of nuts, I was just going over the Power transformer and it's taps.

Primary being fed 240v [analog meter] 236 [digital]

The secondaries are written on the transformer as 260v and 130v. In the circuit I've got it gives them as 235v and 125v. Measurement says 265v and 133v.
Circuit says H.T.1 should be 648v, reads at a crazy780v in standby [ which is right at the voltage limit of the caps across it] and 750v full on.
H.T.2 should be 342v before it gets split off to various places, it's reading 400v.

I'll get the new stuff and measure it all again

I know that the no load voltages will be a little higher, but you have it loaded and operating. I have a hard time believing that the PT is failing, but surely power caps wouldn't cause that, would they?
