We use our SUPERMATCH process to match one of the ECC83’s and the 6L6GC’s. We supply a test certificate showing the matching test results. The hand matched ECC83S should be placed in the phase splitter position next to the 6L6GC output valves.
We test every valve on our suite of AVO testers in order to ensure top quality
"Prompt delivery, boxed and secure, included a tip sheet and a handwritten thank you. All valve sellers should be like this. Highly recommended." - Steven L.
"I don’t think I’m the only guitarist out there who knows his/her guitars, but very little about tube amps. I ordered a Supro valve kit (which is great), but it’s the service, help & advice I received from Stewart that was outstanding. I was going to say ‘these guys’, but it didn’t seem right, as my communication was just with him. Thank you!" - Robert G.
