[Collins] Re: 51S-1 improvement

[Randy Zelick]

Hello there,

Well if you are looking for warm bodies, I have a nice 51S-1 and would 
invest some $$ to preserve it. 

As usual for these sets the power transformer gets hot. There was a mod
posted to substitute one audio output tube for another which is supposed
to help, but I have not tried this. I do have a copy of the mod in an old
email if you need.

Notice that it is easy to unbalance the filament string in the 51S-1. They
used a complicated system to permit 24 volt filament operation.

Cheers,

=Randy=
