I have a Lakeshore Bandmaster II-B, the one with the VFO. I don't know whether its size + weight and the not sane number of my other projects will dictate i sell it. I also have an audio phase shift network in a little package like a metal tube. I don't remember the maker right now - this is what happens apparently when the % of memory space used approaches the capacity - but you will know it anyway. I was wondering about the longterm stsbility of the 1% resistors in the audio phase shift networks. Knowing about old - style carbon resistors, i am not optimistic.
