You might also consider an RCA SRR-11/FRR-21. They are 
contemporaneous with the R-390A, but use all submini tubes and a 
projection type readout.

I've always like the SRR-11/12/13 receivers. The HF version, the SRR-
13/FRR-23 isn't as stable as the R-390A but it sure is fun to operate.

When working properly and properly aligned, it has been my 
experience with them that they are very reliable receivers.

However, as Roy Morgan mentioned, the ANTENNA is really far more 
important at VLF then the receiver.
