We have a huge parts inventory that includes many brands of new old stock and reissue tubes, high voltage axial film and mica capacitors, hard to find connectors, power resistors, tube sockets, vintage style knobs, and much more. We’ve got loads the documentation for pro audio tube gear and have established a thorough restoration program to return them to their original specs, and sounding like new.
A typical restoration includes:
Replacement of all electrolytic and “paper” capacitors
Careful testing of each tube and replacement of missing tube shields, with complete “retube” available on request
Replacement of brittle or damaged wiring (using wire with with a similar appearance)
Calibration of all gain reduction and metering functions
Power supply check out and VU lamp replacement
Cleaning of switches and pots
Installation of 620 ohm output termination resistor, with high quality XLR adaptor cables installed on request
Performance test including frequency response, signal/noise ratio, gain, distortion, output level, and headroom.
Faulty meters are a common problem with older gear. In most cases, they can be repaired.
Frequently, we service tube gear that has not been used for many years. When we perform initial tests on a vintage tube item, the first power up is done gradually and safely, to prevent damage to rare and expensive components. While the appearance of some replacement parts will e do out best to preserve the vintage appearance of some new parts will differ from the original components, we take pains to preserve the original look of vintage gear. In some cases, original “can” capacitors and other discontinued components can be “restuffed” with new parts, to retain their original look.
The buyer of this service is responsible for shipping both ways, and shipping costs are additional. Labor and materials are guaranteed for 60 days. Our return rate is very low but in the event you have a problem, we’ll get you taken care of as quickly as possible.
Please, be extremely careful when shipping your vintage tube gear. The tubes should each be unplugged, wrapped in bubble wrap or newspaper, and placed in a separate box. If the VU meter is exposed, it too should be removed and also packed separately. The main chassis should be generously covered with bubble wrap or Styrofoam, and shipped in a double wall box. Double boxing is ideal.
This ad listing addresses a large number of models, and repair and restoration costs vary widely according to the condition of the item. The cost generally starts at $500, but can be much more than that. It’s hard to give very accurate estimates before seeing an item in person, but if the customer emails us a few photos along with information on the history of the unit, we can usually give a ballpark estimate. These tend to be expensive repair jobs but these units are usually worth several thousand dollars, so repair and restoration is a good investment. Feel free to phone us at 818-843-7981, or just send us a message via ebay if you would like more information.
