How old is the Texas Star 500 ?
What transistors are in it ?
Does it have a variable on the front of it ?

Hi Ranch 55 It is an older TS 500 dx. Not a variable power model. Toshiba 2879 transistors. It just quit working. I tried to repair, but no luck. When you turn it on one of the wire wound resistors will start to smoke.
you might have a blown transistor.
remove all four 2SC2879 transistors and test them with a DMM.
(instructions for this are all over the web)
find the bad one and throw it out.
sell the rest on ebay.
buy a new amp with the profits.

Hi. I am very old school and do not have a smart phone to send pictures. Sorry. I can tell you that on cb tricks in Texas star 500 DX listed in parts you will see in transistors (R21 and R28) are listed as 25 ohm 5 watt wire wound resistors. R 21 is the one that got hot and started smoking. Hoped that helps.

I agree and then sell the 500 on e-bay as fix or repair showing up front that it has no finals. If he really wants to fix it best option probably will be a new matched quad of HG 2879's.
No sign of over heating. The (R21) wire wound 25 ohm 5 watt resistor or choke resistor gets hot.
Hi Ranch 55. Do you repair these? I am only learning and can be missing something you might find?
