R390A Services Offered
- Restoration, Service, Parts-

If you are on this page, you are interested in contacting me about restoring a receiver, rebuilding capacitors or modules for your own personal receiver. Please read through this material before doing so.  At the bottom of this page, there is an "E-Mail Me" contact link.  Also note, because of scarcity, I DO NOT SELL R390A receivers.

I have enjoyed the lore of the R390A for some years.  These are superb performing receivers which can last a lifetime if properly cared for.  As an adjunct to my own participation in the radio hobby, I restore R390A’s on an informal basis.  Happily, there is an ever-growing number of do-it-yourselfers who take on this rather large project themselves.   I am willing to help these fellow enthusiasts by performing some of the less understood procedures and alignments on individual chassis for them.  Please call first or drop me an E-Mail to make arrangements before sending anything.  I am also able to offer limited advice by phone.  The best times to reach me is via E-mail.

One caution:  Before taking on an R390A repair or restoration project, understand that the precision design ties receiver mechanicals and electronics “at the hip” making it one of the more complicated and difficult receivers available to the average hobbyist to understand and service.

Pricing, where applicable, is posted next to each individual item with return shipping, packing “insurance” charges in (quotes).  Note: Due to export entanglements, shipment to destinations outside the United States is not offered at this time.

Filter Capacitor Rebuild: (Strongly Recommended)

Most vintage equipment is dated by the available life of its electrolytic filter capacitors. These components age and fail even if the receiver has never had power applied to it.  With the R390A, I find the most common source of intermittent snapping, popping and over-dissipation of the power supply is caused by the 2 multi-section, electrolytic filter capacitors, C603 & C606.  These easy to remove and install, plug in components are located in clamps on the R390A audio chassis.  Once removed and shipped to me, I disassemble each and replace the internal components with modern design, quality Mallory components.  The capacitor is then re-assembled, re-potted and each section is individually tested for leakage and value on an Hewlett-Packard capacitor checker.  This procedure gives your receiver a new lease on life while preserving its original look using the original capacitor cans.

If you do nothing else to the receiver,  have your filter caps rebuilt while the limited supply of replacement internal components lasts.   Price is

$75($3.50) per pair.To the right are 2 finished, rebuilt filter capacitors.
