[Anyone know of a replacement or a good substitute for a STV 03h biasing diode. NTE no longer has replacement. Thanks
A varistor is basically a surge protector for voltage spikes.
If you can figure out your peak/peak voltage and amperage from your circuit, you should
be able to get a cheap NTE equivalent. (Which will be rated above your p/p voltage).

OK I see it there its circuit part # H728, shown as 3 diodes in series
Its providing thermal control over the driver transistors, decreasing the drive to the final transistors as they heat up.
I was trying to figure a way to explain it and gave up after 3 deleted attempts haha
maybe some one else could do a better cct description

Do you still have varistors STV-3H-0?diode
We have a stv3 if you are interested
Did you find any varistors STV-3H-0? If so, I would like to have.Hi Stephan, do you still have the STV3? I need two for a vintage JVC amplifier. Can you please email me at flyingtele at yahoo dot com dot au
Thanks very much.
I wrote an answer on the page this was posted on thats the best I can do as of now.Did you find any varistors STV-3H-0? If so, I would like to have.
Did you find a supplier?
