Hi Dave: Picking your brains again: Working on a MPX 65 with no separation ( again)
All new tubes , good pin contacts, recapped audio path and resonance caps and electrolityc, good 19k pilot stable lissajous locking @ 38 Kc ( no free wheeling) equal signal both sides , checked diodes OK . At mpx output I can not obtain a regular even sine, nor separation at all. This happens with both 300"s. Any hints?? Thanks Martin
