[Milsurplus] Soviet R-326M Rcvr.

[WF2U]

I have the older, tube model, the R-326. It is the same size and shape factor, except it has pencil tubes and no digital frequency display. It has an internal inverter supply providing B+ from the +/- 2.8 V with center ground pair of wet cell rechargable batteries. The external AC power supply provides the dual 2.8 V and also charges the batteries (with the PS the receiver will operate without the batteries). The primary of the transformer in the PS also has dual windings, but there is a primary voltage switch on the front of the PSU which changes the connection of the primary from series (220 VAC) to parallel for 110 VAC input. 
Looks like on the later R-326M  the primaries have to be hard-wired to switch between 220 and 110VAC.

73, Meir WF2U/4
