Hi Bruce
Thank you for confirming the 8484A is a Diode front end and On re reading your previews mail again it is as clear as MUD
Do not worry about Typos as I must be the worst speller on this sight

It is a type - I meant Diode
The 8484 is a DIODE sensor - many other HP diode ensors have a D in the model number as explained B4

OK Bruce please explain !
You say (The 8484 is a dione power sensor. Many other HP diode
sensors end with t "D" instead of an "A" in the model number.)
I do not understand ?? also is dione in the above line a typo
So Is the 8484A power sensor is a diode front end ??

with t "D" instead of an "A" in the model number.
E.g. 8485D as opposed to 8485A

From memory the 8484 power sensor is a diode front end
But a working 8481 or 8484 go for about ?120 to ?160 in the UK
equivalent to a day’s wages
And it would take best part of a day to modify busted thermocouples
for a diode by the time you did any calibration

An interesting and long running thread.
Like many, I have a bit of a soft spot for the old HP435 meters and
would like to have one working on the bench.
Since broken detectors do show up now and again at a decent price,
has anyone successfully reworked one with busted thermocouples and
modified for a diode front end? I know it’s small and very fiddly,
but is that not easier than trying to build one from scratch?
