Forte 1a amp service?

I have a Forte 1a amp that buzzes on one channel as it warms up. Does anyone know of a resource able to fix Forte products?

Contact Jon Soderberg at Vintage Amp Repair. He's a former Threshold / Forte' tech and can take care of you. Keep in mind that it may take him a bit to get back to you though as this is not his main job anymore. Sean
Sean, Thanks!
