I stumbled into some great info here on the problems with these amps and hoping some guys are still around? I am trying to spec the problematic D11 diac on the daughter driver board for the PSU mosfets? It is now black and cannot read it.
If anyone has experience with these, I might have a few other questions.

Diacs.
BR100 and BR103 were the main two produced.
Made by Philips, they are a bi directional trigger and work similar to a low voltage neon.
When the voltage reaches the threshold voltage, they go short circuit for a split second, producing a pulse, used mainly in light dimmers and motor controllers.

I do understand what a diac is. I am more interested to know if someone has the proper spec for a replacement or the means to test is scrap amp? Someone has mentioned a DB6 which is a 60V trigger, and another mentioned a DB4, which is a 40V trigger. That will make a radical difference in an oscillator circuit.

Here is a thread where that is stated.
There is another thread on this site where someone supposedly tested one and indicated it opened at 40V, indicating it as a DB4.

Here is the data sheet for the Aston Martin.

It’s a DB6, rated at 56v-70v, or 63v+-7v.I stumbled into some great info here on the problems with these amps and hoping some guys are still around? I am trying to spec the problematic D11 diac on the daughter driver board for the PSU mosfets? It is now black and cannot read it.
