Default Grampian 554B PA amplifier. 240 or 12V

Hi

I picked this is up at an auction, in a job lot.
No interest to me, but I became curious enough to connect it to a 12V battery, vibrator buzzed away, rectifiers lit up, voltage on first smoothing cap climbed to 400v. I managed to control myself and disconnect it before I started looking for valves :-(

Missing: - pair of KT66, EF86, ECC83, case.
Looks original, but repaired as needed over the years.

Too good to break up for bits?

20 + delivery or collect or FCS
