Keen's GeoFex pages) plus cleaning or replacing the switches and pots (plus giving him my list of amp issues, of course) be my best course of action? ![]() Would asking the repairman to do the replacement of all of the preamp's polarized and nonpolarized electrolytic capacitors (as recommended in R.G. I was going to take the amp to him and lend him my copy of the Royal Guardsman schematics (bought on line a few years ago), but I've read here that some parts of the schematics might be inaccurate. The power switch illuminates in the Standby and On settings, but the amp is on as soon as the switch is turned from Off to Standby and remains on when turned to On.Īll of which is disappointing, of course.Īs it happens, Baltimore has a locally owned music store (Bill's Music, Catonsville, MD) with a repairman who has worked there since the late '60s, so he's probably seen the innards of a Thomas Vox amp before, but not for a few decades. The reverb makes ghostly background noises as I insert and remove the guitar cable plug at the amp's input jacks but otherwise has no effect. The midrange boost switch makes a pop when switched (can't tell whether the boost is working, since the Brilliant channel is effectively useless) the various volume and tone knobs on all channels exhibit various levels of scratchiness, nonlinearities, etc. Top boost switch works.īrilliant channel: effectively no volume (guitar volume through speakers at maximum amp volume setting is not much more than the unplugged guitar level, if at all).īass channel: the most volume of the three, but still below the equivalent on the Royal Guardsman (the bass channel is weak on the Buckingham). Normal channel: low volume-maximum Viscount volume on this channel is equivalent to a volume control setting of about 8 o'clock (i.e., barely on) on the Buckingham's normal channel no tremolo (without or without the use of the footswitch button) hitting the distortion button on the footswitch boosts the volume a little and adds a tiny bit of distortion, but maximum volume is still low treble control seems to roll off the treble as the knob is turned clockwise. The Viscount has an extensive list of issues, and I'm looking for general suggestions rather than asking for detailed replies concerning repairs. Picked up a Thomas Vox Viscount combo (plus an original four-button footswitch, which clinched the deal) recently as a backup for a beloved Vox Buckingham head plus cab (also have a Royal Guardsman head without a cab).
