John,

Thanks for the effort.  I have the info sheet.  I am looking for a service
manual ideally but likely will not find it though I thought I would ask.

Joe

Hi Joe - I have the "Information Note" that comes with new 58535A units. I
wish I could scan and email it, but no scanner right now.

The most useful info is the specs - below.

BW +/- 10 MHz -3 db
Gain 0 +/- 3 db
NF 5 db typ.
VSWR 1.2 input typ. 1.6 typ output both at L1
Isolation -30 db at L1, -54 db 40 Mhz from L1
DC Power +4.5 to +13 VDC
Current 23-48 ma depending on Voltage.
AC Input level - Max -25 dbm, damage level +17 dbm at L1
(Mech and Env omitted)

Anyone with manuals or schematics for these units?

Anyone with any experience repairing them?

Thanks in advance.

Joe
