Replaced a few more caps in the power supply with no improvement so I turned my attention to the tubes for a while. It's a rather curious mix.
First, we have one 25Z6 and two 6AL5s branded with MECK   All of the remaining octals are RCA with the same '9-26' date code. 26th week 1949 ?  Then a bunch of MIRROR-TONE branded 6AU6s dated '9-35'. I don't recall ever seeing this brand before.  They all test very good. Could they all be the original tubes? Also found this label inside. The original owner?
