[BDM]

Question, I've noticed while adjusting the IFs on both my Zenith chassis 5905s, adjustment "B" of the IF never peaks with a signal generator. In fact it's strange, it actually tunes down. Meaning the lowest reading you get on the DVM is the peak. I've confirmed this several times on actual stations. I've learned to peak A C & D first, then peak B on a station. Thought I was nuts until I noticed the same thing on the 1204 chassis. Same front end but the 12 tube version. Anyone have an idea as to why? They function fine, but it's always been in the back of my head.
