Should have made not of this in the previous message. The markings
appear to be HP 385. Likely part number is 1901-0385


Eric,

I can confirm that this is/was the right part number. In the '70's a matched
pair was ~UKP 150.

You might try something like a pair of BAR28, if you can get them, (Shottky
barrier - useful to 10GHz) at UKP 0.5 each IMO they would be worth trying.

Good luck,
