Whats a good brand for a tube biasing aid? I remember a tool that you could plug into the power amp sockets on your amp and then plug the power tubes into the device and it would rate the output of both the tubes and the amp and match/bias them. Can someone tell me what brand that tool was or give me a good brand of tube biasing equipment?
I got mine from these guys. Quality product, great instructions, awesome customer service and fast shipment.
Testers arent that great im looking for ones that are like $100+
