Rear Panel:
Fuses: ½ Amp fuse for DC Voltage section
3 Amp AC fuse.
Speaker Jacks: Plug speaker into specific jack for it’s rating (8ohm speaker
into 8ohm jack.)
Effects Loop: Plug “In” to Send and “Out” to Return. Good for Delay or Reverb
effects. Run all others (overdrive, wah, etc…) through the front.
Care and Feeding:
While we hope you get years of worry free use out of your Dr Z Amp there are
some basic maintenance procedures to follow.
Changing Output Tubes: If your amp starts sounding a bit dull or lacks punch
it’s usually time for a new set of output tubes. Changing the EL84 output tubes
on your Stang Ray is easy. These amps are cathode (self) biased so there
is no need to rebias when changing tubes. Always use a matched quad of
EL84’s. We use Groove Tubes EL84S as our standard EL84. Always make
sure the power is off and AC cord is unplugged when changing tubes. Always
use caution not to burn your fingers as tubes become very hot quickly. With
moderate usage output tubes should last 6 months to a year.
Changing Pre Amp Tubes: When pre amp tubes fail it usually results in a static
type noise or a ringing microphonic type sound. Pre amp tubes are easily re-
placed. We recommend replacing them with the same brand/type that came in
the amp. We have hand selected these tubes to deliver optimal voicing.
Changing Rectifier Tube: Signs your rectifier tube (5AR4/GZ34) needs
changed are fairly obvious. A bad rectifier will usually result in a fuse blowing.
Power off, unplug the AC cord and replace the blown fuse before replacing the
rectifier tube. Use caution as these tubes get very hot!
