Default The RCA AR88 Communications Receiver.

The designation AR88 means Amateur Receiver Model 88. It is also known as the CR88 meaning Communications Receiver Model 88.

The manual for the RCA AR88 Receiver can be downloaded from The Boatanchor Manual Archive located at:-

The "Bath Tub" capacitors used in these receivers tend to leak electrically as they grow older. These capacitors are no longer available, but it is possible to fit new modern capacitors inside them. Drill a couple of holes in the back of the case and drain out the oil. The oil may be harmful, so wear protective gloves and dsipose of the oil safely. You can then insert a small pair of cutters into the hole and use them to remove the back "tin opener" fashion. Finally peel the back away from the bathtub section by splitting the solder seam. It is not advisable to try to remove the back by unsoldering it. A great deal of heat will be needed and this will melt the insulation around the solder tags. Once the back has been removed the old capacitors can be removed and new ones soldered in. Screw the casing back to the chassis without the back (it only keeps the oil in) and you won't know the difference from the original.

There are numerous webpages relating to the AR88 including those at Ray Robinson's virtual museum:-

Spare parts are available from Colomor. They can be found here on eBay:-
