Amplifiers for EDC MV105, MV106, VS330, E100, 2902, CR103

Description

(The amps in the first 5 pictures are the ones for sale.)
These are dual IC amplifiers built by me that are close to the circuit design of non encapsulated ones used by EDC. See pictures.
These have a modified circuit design and use modern and much better IC amps, especially the chopper stabilized IC amp.
My circuit uses military grade passive components.
These work with the 501J as well; however, the integrating capacitor on the 501J is 1000pF instead of 0.1uF as used on the other EDC units, i.e. MV106 etc.
Using the proper integrating capacitor as indicated above makes my amps usable in all EDC units with plugin amps.
My preference is to use this design for the units listed in the heading because they have inherently higher loop gain.
My EDC units are used as the test bed for my design efforts. I have 7 501Js, 1 MV105M, 2 E100s, 1 VS330 and 4 MV106s.
Testing in all these gives me confidence for what I do.
Any questions please ask and I will answer.
My units are guaranteed to work or your money back. None of the ones I've sold were returned, nor asked to be returned.
I made more units than I needed plus had a lot of fun doing this.
I have my single IC version on another listing. Those were done later than the dual IC versions. Both work great, quiet and stable.
Thanks....
