Title: Bell and howell Schools 9512/9514 Multimeter
Post by: Robbdoe1 on August 14, 2022, 08:07:42 pm

Hi,
Does anyone have any information on this meter. It's transistorized. I'm trying to find out what transistors it originally came with?
Thanks.
Robb

   I assume that you're talking about the real Bell & Howell from the 1970s and 80s and not some late comer Chinese knockoff.

    I don't know about their multimeters but B&H usually used someone else's equipment but marked up especially for them.  I would look for someone else's meter that looks close to the same and see what transistors it uses.  Heathkit might be a good place to start.

    I owned a black B&H computer at one time and it was a relabeled Apple II with a black case and black keys tops with white lettering (the reverse of a normal Apple II).
