Dr. Z Prescription JR Head in Red
The
Prescription Junior
Strength (Rx Jr.) The Rx Jr has all the same sonic characteristics of
the ES, but at half the power. The Rx Jr features a post phase inverter
master volume, 3 dB footswitchable boost, EF86 post EQ gain layout, a
pair of cathode biased EL84s, and a 5Y3 rectifier. The post phase
inverter master volume let's you maintain all the integrity of your
tone with the ability to control the overall output. The 5Y3 rectifier
gives a sweet bloom to the low end. When you don't need a full
dose...the Rx Jr is just what the Dr. ordered.
The RX JR uses two 12AX7 tubes in position VI and V3.
In the center of the RX JR design is an EF-86 pentode gain stage in position V2.
The EF-86 has an increased bandwidth and double the output gain of a typical 12AX7.
The Overdose gain boost is connected to this stage, engaging this boost is likened to engaging the best OD pedal.
The output tubes are Groove Tube EL-84-S (Tesla variant), matched and balanced using a rating number of 6.
Finally, the RX JR uses a 5Y3 rectifier in it's power supply. Giving the over all amp a slight sag, the 5Y3 adds bloom and natural compression to each note.

Prescription Jr. 1x12 Combo in Red
Other Head and Combo colors are available too!
