Marshall JCM 900 Lead 1960 412 cab in to have a couple G12T-75’s swapped for a couple V30’s to make it sound 50% better.

A 60’s Vox AC10 Ten Twin in for a checkup and to add a female-to-male 1/4” plug interconnect to the speaker lead allowing for use with an external cab or attenuator. I would prefer only using a 1/4” jack mounted to the cabinet or chassis but I respect the customer’s request to not modify anything permanent like that. Otherwise the amp was previously serviced correctly so nothing was touched again at request of keeping it all stock. The noisy controls and jacks were cleaned, tubes tested.

Mesa Mini Rectifier 25 had some random crackling sounds. A whole new set of preamp and power tubes were supplied by the customer to resolve the issue. Plate resistors toward the front-end of the preamp were upgraded to Vishay metal film resistors for lower noise. A cap was also added in the phase inverter to cancel out high frequency noise.

A pair of Peavey ValveKing 112’s both had issues of no audio. One had failed caps in the low voltage supply, bad solder joints, worn power tubes, fatigued and corroded jacks. The other had 3 bad pots, worn power tubes, and again jacks that needed replaced. New input jack for one and new effects loop jacks for both. The one with bad caps had all caps in the low voltage supply replaced, both got new power tubes, and a bad preamp tube was also replaced.

Fender Blues Junior came in not working. Got a new pair of power tubes, bias mod, cleaning of controls, and a modification to the phase inverter to fix an oscillation issue these occasionally have.

Today’s repairs included a Victoria 35310-T and a Marshall JVM215C. The Victoria was here for a checkup and it received new power tubes to replace the cooked 6L6’s that were installed burning the rear panel. Controls, jacks, tube sockets cleaned, everything tightened up, some solder tended to, and a 12AY7 returned to the V1 position that had been replaced with a 12AX7. Super tidy inside as always but forgot the pics. The Marshall had an intermittent issue of dropping output which I was never able to replicate after hours of runtime and coaxing out any problems. It was due for new power tubes so that was done along with a control and jack cleaning. All common points that lead to volume drop issues were tended to anyway to see if the issue persists for the customer.

This Blackstar HT20 was purchased used online by my customer and arrived with a non-functional overdrive channel. Found multiple bad joints on the preamp tube socket connections so the solder was removed and fresh quality solder reflowed in its place. The power tubes were also seemingly original with plenty of use so a new matched pair was installed and biased.

Amplified Nation Phoenix Fury 50 watt head had some tube rattle that was bothersome to the customer. So all hardware was checked to ensure everything was tight to not aid in the rattle. Power tubes were swapped for a pair of Tung-Sol 6L6GC checked for the least amount of rattle, tube dampers were installed, and bias adjusted.

Peavey 6505+ had issues with crackling/popping noises along with volume loss. Found the connector/harness between the main board and power amp board to be damaged which is a common issue on these. In addition the wires to/from the preamp board were also bad causing random oscillation, popping, crackling. So all connections were hardwired between boards to keep the issue from reoccurring. A noisy preamp tube was also replaced and bias checked.

1956 Fender Tweed Deluxe 5E3 came in for a service after being found in a barn. Someone had previously installed a Norelco speaker with a crossover and tweeter but otherwise the amp was original. New electrolytic capacitors, dropping resistors, grid stoppers, plate resistors, volume control, power tubes, grounded cord, fuse holder, fuse, leather handle, and Jensen speaker were all used to get this back to functioning like new.
