[Test-Equipment] HP 10554 Oven

[pete wokoun]

Bill,

  You can fine the Master Consolidated HP X-Ref list here, all 143 pages of it:

http://www.sphere.bc.ca/test/hpparts.html#cross

 

It looks like you add a 185 prefix and add zeros after the dash to get 4 digits.

3-347=1853-0347=MJE700

5-10=2N2646

4-560=MPS A12

4-23=no listing

 

I have a tech manual somewhere for that oscillator, will look for it and see if there's anything more in it.
