Cloning the HP3325A Option 002 - HV Output

<< < (4/18) > >>

LazyJack:
Yes, the B version uses exactly the same board. It has the same part number.

Rollin Hand:
Are this boards for sale?
Thanks

Neomys Sapiens:
On the topic of the MAT01: even if this 'supermatch pair' is not really needed, a double transistor might be beneficial to the application. Some that are a bit easier to source: MD8002 (Mot), 2N4045, 2N2915, BFY83, SL301L, although I haven't checked their respective suitability yet.

I'll release the gerbers and source files (if anyone else uses DipTrace) when they are finished and I'm sure I'll end up with a few spare boards when I get mine made that I could send to people who want one.
Maybe I can order a few extra sets of parts too and send them out as a kit for people to solder together themselves?

Cool, I'll take a look at thoise suggestions and see what matches up.
Failing that, using superglue to marry a somewhat matched pair of transistors could work in a pinch. :)

VK5RC:
Thanks for the post, @Terra if you are ordering boards and components and can easily add another set - I would put my hand up for one set of both parts and pcb.
