[Collins] Collins 30S1 technical information needed

[John King]

I have had Collins 30S1 serial # 260 for many years. About 20+ years ago, I had to take it from basket case to a great operating amplifier. It recently failed and I (now at 86 years of age)  am in need  of someone familiar with the 30S1 to discuss the technical problemthat I now have with.
If you or anyone you may know are knowledgeable of the 30S1 I would greatly appreciate your discussing the 30S1 with me. Please provide me with information who might be of help to me.
Please consider this a desperate request from an old ham and if you can, please acknowledge this request.
Thanks very much and 73, John King K5PGW
