Has Texas Star closed their doors? You have some unique amps because I have not been able to find a source for a new Texas Star amp. Is the wiring upgrade an improvement from OEM?

The wiring upgrade definitely improves the performance of all the Texas Star amplifiers......
Yes, I have at least a couple of each size......
Copper Electronics shows to have a 350V available for $360 plus shipping......with no upgrades.....

What exactly is the wiring upgrade? Is it an optional "upgrade kit" available from Texas Star?
 
Is it safe to assume the "upgrade" was the replacement of the original positive and negative power cables?
My thoughts.

The power wires are too small, my now very old 500 has 8 gauge directly to each board.
The factory fuse holders have been by passed and removed because they will fail under hard use.
I ran the positive directly to the second battery with my fuse at the battery and the ground goes to the frame.
Original Toshiba 2979 transistors are now $200 each from ICA and RF parts sells used 2879's that have been tested for $129

  • @ Geoexplorer69:
    Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
  • @ Geoexplorer69:
    Is 30 ohms worth worrying about in a 100’ run of rg8u ?
