Description

MKR now offers mail-in preamp rebuild service for BV, CV, RT, and DV organs.  Due to the difficulty of accessing components on these amps and their advanced age, only Full Rebuild is available. Every component (resistor and capacitor) is replaced, with the exception of any oil-filled tub capacitors, as long as they test well. A fuse is added. Due to long length of resistors, mil-spec extra long lead resistors are used. Worn or noisy tubes are replaced as needed. Tube sockets are cleaned, tone control pot is cleaned. Preamp is fully tested both on bench and in an organ before sending back.

How it works:

1. MKR will ship a box to you containing a hardshell soft foam interior case with pre-cut packing foam, detailed instructions, and a prepaid return shipping label.
2. Follow the instructions to carefully uninstall and pack your preamp.
3. MKR receives preamp and performs Full Rebuild. Please allow 4 to 6 weeks for rebuild service to complete.
4. MKR ships preamp back to you. Follow instructions to carefully reinstall preamp into organ.
5. MKR requests that the box and hardshell case then be shipped back at your own expense. Once received, you will receive a $100 refund.

Free phone or email technical support is offered with all services. A 2 year warranty is offered on Full Rebuilds. Warranty claims will be repaired, but owner is responsible for the cost of shipping.
