I had about a 10 minute chat with Bob at Henry Radio Wednesday afternoon. So here is what he had to say:
1. Henry Radio did not negotiate or in any way shape or form purchase T.P.L. Amplifiers. As such, they have no drawings or schematics for T.P.L. Amplifiers. They have no spare parts, boards, or otherwise for T.P.L. products.
2. Henry did purchase the domain registry and old voice phone number to T.P.L. The phone forwards straight to Bob's cell.
3. Henry DOES repair T.P.L. amplifiers. Turn around time is a little longer (a few weeks to a month on average) than on Henry products, because with no schematics, they basically are reverse engineering the circuits in the diagnosis process. They have 2 dedicated 2-way technicians that work on the T.P.L. products, while the other bench technicians work on the Henry line.
4. The old man Henry has retired. Bob is apparently in charge now, and will chat with anyone that has questions. No R.M.A. number is required. Just go to the Henry website and print out a hard copy of their repair form and include it with your T.P.L. amplifier for service.
5.Also, Henry is once again repairing their own name brand 220 MHz amateur amplifiers. They had ceased repairing them about 2 years ago, and refused repair on one of mine that I had purchased from them back then.
If you have further questions, reach out to Bob directly during Henry's normal business hours.
