Avoid Rick Mish of Miltronix, Toledo, Ohio if you are in need of an honest repairman for your Collins. Our company sent this crook an R-390A for a
rebuild and received a radio that was only partly done. The audio deck was never serviced and the two defective capacitor cans caused the power
supply to burn up in little time. The two 40 uf caps were more than double
their value at 114 uf. Of the 30 uf caps, two were dead and did not even register on the meter. When Mish was contacted about this he said the radio
was working fine when it left the shop and that he was not responsible.
