Re: Another Tweedle Dee

Thanks alkuz, I understand the reason for the cap to short againts the ground plane and that would be bad.. Resistors are all .5W or higher. I do have 1W that could have used for the plates though. I do have a hard time getting good components at a reasonable price.. and for some reason stores are s...

Re: Another Tweedle Dee

I did not realised that by adding that 100pF capacitor I would cut lots of frequencies when volume was not maxed. Started chasing the oscillation, it should some how be related to the MV I added because no one ever reported this problem with this build. It was indeed. My MV was routed to the 4th inp...
