I have a brand new - never used - TLD 1693 VHF amp that I purchased as a "back up" for a local club. I tried to find - buy - and substitute other final transistors and discovered - there are no more around. They had the MSR2000 repeater and this amp has the M1131 - M1133 - M1134 transistors in the same configuration as the MSR2000. It was something that I purchased with my own money - They have changed repeaters and I was stuck with this extra amp.
