[Boatanchors] boatanchor jukebox improvements

[Dick KF4NS]

I guess a Seeburg Q160 from 1962 qualifies as a boatanchor. This 
belongs to my brother in Ohio and I am trying to get it updated for 
him. I have all the tubes needed for a complete replacement so we are 
ready if one fails.

I already built him a bucking transformer/over-voltage protector to 
set the AC input to 115vac. I am going to add an inrush current 
limiter (ICL) and have added surge protection.

He did some inquiries on various rebuilds and protection, and a 
gentleman offered to upgrade it for him with transformer protection 
from shorts in the control center for all transformers and the same 
for the solenoids to prevent overheating but the guy wants $350 ! I 
told him to hold off while I do some research.

I have used crowbar circuits to protect the equipment from overvoltage 
in the power supply but that may damage the transformer if the line 
fuse doesn't blow quick enough. This unit has several power supply 
transformers for various sections of the unit so each should be 
protected.

As far as the solenoids go, I have no clue how to protect them. The 
transformer protection, I guess, could be handled by the new resetable 
fuses in the secondary but I am sure you all can provide other 
suppositions.
