I purchased an Epiphone Valve Jr., version I, for $119, and a mod kit for it
on Ebay from Alnicomagnet for $50. It sounded good out of the box, but with
a hum that Epiphone has fixed on version 2 and version 3. The Alnicomagnet
mod kit:
*1. **Drop HT Voltage to a safe level*
*2. **Fit HT Fuse and chassis mount fuseholder
*3. **Reconfigure input to Fender Champ specification
*4. **Re-bias pre-amp tube to "Blues Harp" specification*
*5. **Change interstage attenuation resistive network to clean up sound
*6. **Fit Standby Switch*
*7. **Fit Output Impedance Selector Switch (choose 4 or 8 ohm cabinets)*
*8. Fit Line-Out Jack*
*9. Fit Pentode/Triode Mode Switch*
*10. Change heater (filament) supply to DC as later Version.2*
*11. Add extra HT filter stage as later Version.2 *
