1 rodney wylie 4 months ago I have a Deluxe Re issue Ltd Edition the wine red colour, I bought it used, re valved with correct JJs and bias correct and sounded super with my Strat, Tele, 6120DSV, 6119T Filtertrons and my Epiphone Elite 335 with Humbuckers. Had volume at 3-4 in Studio set up using the reverb and tremelo to good effect straight into input 1 and also on the non reverb channels all fine.Its lost the headroom, sounds slightly driven especially playing chords. All tubes a glowing, tap test done and new 6v6 power tubes tried with no avail, did the tests on the AX7s and AT7 with new tubes to no avail, impedance on the speaker seems fine. I then check cleaned all the valve sockets, only thing I can't do is the bias, seems you need a plate tester. Any ideas.Likely needs a tech"
