Can anyone tell me how to lower the dead key on a Cherokee 1000 base radio. Can it be done with or without parts? How low can it be lowered to? Would like to add low drive amp to it. Thank you for any help here.

Hi to all. I understand that the IRF9530 MOSFET can be used to replace the ERF9530 MOSFET transistor. Is this true! The physical size of the IRF9530 is much smaller than the ERF9530. Does this make any difference with using the IRF TO REPLACE THE ERF power transistor in a amplifier? Thanks for...

Thank you Sir.

Hi to all. Does anyone out here have a wiring diagram for a Turbo 8 Mosfet amplifier. I have one that seams to have a part missing in the front of it. Looks like it could be a capacitor from the hole on the superior pcb board, but not sure? I am unable to locate any info on it, but it looks like...

Thank you.

Nomad, do you know if a Peak transistor tester can test both HFE and Vc or do you need to test Vc on a separate meter? Do you like the model 75 peak meter?

Thanks again Nomad! Much appreciated info.

Thank you so very much. I learn a lot on this forum thanks to you great people!!

Thank you for the information. Can you also tell me me what PBF stands for on a transistor following a set of numbers like 9530PBF?

Hi to all. No where in the glossary of electronis can I find the meaning of ERF OR IRF on a mosfet transistor. Does anyone know what these letters stand for? Thanks for any help with these two identifications. Chuck Saylor

Thank you for this valued information. Can you tell me the difference between ERF and IRF mosfets?

Hi again. Still trying to learn here. What is the difference between IRF and ERF mosfet transistors? Is a IRF9530 a good replacement for a ERF9530 moset in a amplifier? Would the IRF9530 also work as a replacement in a RM Italy amplifier? As always thanks for your valued advice.

Thanks for the advise sir!

Either of these will work to replace the original RM3s? Is it possible to get these as a matched set of 16? Thanks again.

Hi Handy Andy. Is the Darlington 2N6045 a mosfet transistor that can replace the Italy RM3? For a Italy 703 Kl that has 16 RM3s do I need to find 16 that are matched for replacement? If that is the case where do I find 16 matched 2N6045s? Thanks for any help here Chuck Saylor

Hi Ranch 55. Do you repair these? I am only learning and can be missing something you might find?

Please disregard my first two replys. Sorry, but I gave you wrong information. I need 10 9530s. Do these only need to be matched in pairs? I thought they all had to match. Just 5 pairs if they only need to be matched in pairs. I also need 16 or 8 pairs of RM3s. Do these also only need to be...

I guess 5 pairs if they only need to be matched in pairs?

I need 10 for my Italy KL 703. Thanks for any lead you might have.
