This VT77 valve kit contains one ECC81 (12AT7),three ECC83S’s (12AX7), and four 6L6GC’s , all from JJ Electronic. We use our Supermatch YES process, and the output valves are hand matched and the ECC81 is hand matched. The ECC81 is to be used in the phase splitter position next to the output valves. Matched valves all come with a test certificate.
Valves are tested on our suite of AVO testers
