I just found out the the L-4B has the Harbach mod and the bleeder
resistors were removed to eliminate excessive heat.
Is there anything else I need to do to the power supply?
Thanks!

I would think 20A would be fine unless the run is long, then I'd opt for
30A. Be aware that pin arrangements for the plug and socket change for
the various ratings.
Even if the PS is working ok with the amp, I always replace the 5K 7wt
resistor on the underside of the supply with a 5K equivalent, 20 watt
rating. When the original resistor fails, it takes out the ALC pot that
also contains the standby switch; these haven't been available for decades.

I ran a 20A line for my Alpha 99. Works great.

Just bought a Drake L-4B amp and while I am waiting for the amp to arrive
I had the electrician over. He wants to know what everyone is running for
their 240V line. 15, 20 or 30 amp service.
Thanks!
