Forte 4a service

I have an opportunity to buy a used Forte 4a and understand that they used IBGT transistors, which are no longer stocked by the manufacturer. I also understand that Jon Soderberg of Vintage Amp Repair used to service these amps and had some stock of the IBGTs.

Soderberg's website is no longer working. Does anyone know if he is still in business? If not, are there other avenues for service or for the IBGTs?

Many thanks!


If you have a local tech that can repair it these guys may be able to source the parts

The website for Soderberg said temporarily closed. Not specific as to reason or length.

I have never used this repair service but their web site states they service and repair Forte amplifiers. I suggest you call them to discuss.
