amp question for builders

[Se7en]

i was told the other day while by passing the wimpy fuses inside the amp to also take braided shield from RG8 ( i have rolls of it ) and strap the transistors to the ground wire inside the amp? can i ask why a Texas Star didn't do this? any real reason why not to do it? any advantages?

Serves no purpose other than when a builder uses inferior boards with thin traces in circuit to help the output transistors emitters make contact to ground.

Pretty much snake oil and makes if even more difficult to remove blown transistor.

Yup Mack hit it dead on. As long as the proper board was used, no difference. The only time it would help is when the circuit board is really thin copper plate or when the traces are really small. Seen some boards, the ground traces weren't much more than an 1/8" wide. In that case, it may have helped. And yes, it is a pain when you have to pull it to replace the pills/ transistors.

thanks mack, and Crusher.
the texas star uses small traces on the board. how ever there grounded. so sounds more like i'm being told to snake oil my amp.

The circuitry inside the transistor will fail long before it's path to ground through the collector tabs.
