We started in late 2012 at my home address a few doors down from Guitar Mania. I soon approached them explaining what i repair and can we do some business together and we started almost straight away. It was in Feb 2017 that i moved in to the shop, I think its a good thing for both of us, We both bring business in for each other, have a complete repair service under one roof  Our workshop is based out the back  , I have a very cozy room with a small amount of storage.I try do have a large selection of valves and capacitors in stock along with other parts, So we can turn around the amps in quick time, My Motto is " Quicker its done - Quicker its collected"

VALVE AMP TEST & REPAIR PROCEDURE 
 
  1. Test the amp to confirm faults
  2. Remove the chassis
  3. Visual check over
  4. Test with guitar or bass
  5. Voltage checks
  6. Test all tubes
  7. Check the bias  ( See bias bit below)
  8. Check for known faults
  9. Check electrolytic caps for leaking / failure
  10. Check De-coupling caps
  11. Clean the pots
  12. Check jacks inc any send and return 
  13. Once the fault and cause has been traced
  14. We get in contact and inform
  15. Parts and changed
  16. Signal path is checked
  17. Wattage tested to confirm output
  18. Tested with guitar/bass
  19. Stress tested with scope- signal gen and dummy load for 1-2 hrs +

REPLACEMENT PARTS
We try to keep just out anything we need in stock, Whether its Tubes - Capacitors - Resistors or Jack and Pots
We keep EL34-EL84-6V6-6L6-5881-6L6GC and all common Pre amp tubes, Various different Brands Like JJ-Marshall-Tung sol- Sovtek-Groove tubes- Electro Harmonix.  F&T  and Vishay Electrolytic caps, with mallory decoupling caps. Lots of Brand Jack sockets and Pots and more resistors than you can shake a stick it
VALVE AMP BIASING 
Valve amps have very high DC voltages in them .
Can and do kill.... Leave it to the pro's
All valve amps have a type of biasing in them. Whether its cathode or Grid biasing we check every one when it comes in. To make sure that the power tubes are running within spec. If the tubes are running with too high bias , the amp will sound over driven and the life of tubes will be reduced
