Chris,
You 'might' have some luck if you have any Motorola or GE two way service 
shops in the area, volunteer to relieve them of any -old stock- 3B28's. 
They used them in the highpower base stations from years gone by.

Who might have spare 3B28s available?  I am in need of six to replace the
866's in various amp PSU's.

Please reply off list.
Thanks,
Chris

John,

I have radios, BIG TXs that now use 3B28s in lieu of the original 866s.

The 3B28s are VERY plentiful, and over 8 years of use I've yet to lose
one.  (Two BC-610s)  Neither are they very expensive - UNLESS one
chooses to purchase from the audiophool crowd!

the time to measure it as well as the current being drawn, could you advise
what it was?
