Epiphone Valve Junior 5 Watt Guitar Amplifier Head Hot Rod Used

Epiphone Valve Junior 5 Watt Guitar Amplifier Head Hot Rod Used

Used with wear associated with use. Minor cosmetic scratches/scuffs from handling and play. Noteworthy blemishes or issues will be described and pictured

There are extra holes drilled on the top and bottom, not sure why.  Handle was moved half an inch, looks like the screws may have stripped out at some point.  A tear in the covering next to the logo.  Tested and works as it should.

Hot Rodded Amp

The following modifications were made by the previous owner. The amp turned out real nice.

​Sozo caps for coupling and in the tone circuit.
"tweed" tone mod.
Standy switch mod
R1 1meg metal film (reworked input, moved to input jack between ground and tip)
R2 10k metal film (reworked input)
R4 Changed to carbon comp same value (only spot that benifits from carbon comp) R8 1k metal film (rebiases 12AX7 - more warmth)
R9 750R metal film (rebiases 12AX7 - more warmth and crunch, no fizz)
R10 1k2 5 watt (lowers the B+ voltage; plate voltage on average=305 (with cathode voltage subtracted), plate dissipation on average=11.5 watts)
Added 1k 3 watt resistor to grid of EL84 (saves tube in case of power surge) trace cut
Added 3amp diode to heater feed (lowers heaters from 7.1v to 6.4v) trace cut
C1 Sozo next gen mustard .022uf 400v (same value as stock, better cap)
C2 Sozo next gen mustard .022uf 400v (same value as stock, better cap)
C3 2.2uf 50v (cuts all the low end mud, tightens up the bass)
C4 2.2uf 50v (cuts all the low end mud, tightens up the bass)
C5 1000uf 16v (stabilizes EL84 bias and smooths top end)
Rectifier diodes changed to Super fast
R14 240 3watt (stock bias too hot at EL84, exceeding plate dissipation)
