Amp Supply LA- 1. NT Amplifier. The schematic is on line at radiowrench. LA- 1. 00. 0A/B (the NT is the "no tune" version), but otherwise identical. It appears there is just a single power transformer and the HV power supply is just a full wave bridge with eight diodes, and the HV filter bank is just three series capacitors with equalizing resistors; thus, it's a very simple thing to diagnose as to where the problem is. If you're not accustomed to working around high voltage circuits (this amp PS develops 1. V), I'd recommend you ask someone who is to help you. Not a difficult troubleshooting job, and if its shorted diodes or bad capacitors you're only talking $1. If the transformer is bad, that's a whole different story.
Of course there may be a bad or loose part that's shorting against the chassis or cover also. The "internal" photos of the LA- 1. NT at the radiowrench site look like it's very cramped in there and the plate coupling doorknob cap is perilously close to the top cover. If things move around a small amount, there could be a short, or even a pinched wire.
