I suppose going forward the ST-120 and M125 chassis might be changed to include a second 5AR4, if there is room - this would make having the twin rectifiers practical for most buyers.
Our local Home Depot rents these beasts for $35/day + a pretty massive deposit. But they do the trick.

The key is making the pilot hole - which need not be so neat. The system works from 1/2" to 2". More for the larger set - at a higher rent.

That's fine, of course. Unfortunate that they are pretty expensive, out-of-production and getting rarer, though.
I bought mine 4 1/2 years ago $160 for the pair. I think of it averaging out 20 bucks a year so far and how long they last is unknown.
