Its raining again so no lacquer spraying today...
The 66 has a board with a variety of caps and resistors mounted to 14 connector/lugs. I had read a previous restoration write-up that said you might as well just resign yourself to taking the board off since there are caps under it that you can't reach without doing so. I chose to stuff all the bakelite caps first which went just fine. A 1 meg dogbone was reproduced and replaced along the way (there will be others later) and then I started on the board. I drew out what I could see and then started desoldering leads starting at one end and working my way around. Once I thought I had it completely disconnected....I was wrong...several more unnoticed connection needed to come off and finally the board could come out...

(sorry...looks like I was a little shaky taking the photo
) the big 2 watt 37k (orange-violet-orange) resistor is reading 46k so I will probably replace that. The 100k (white-white-orange) resistors are reading 80k and the 70k (violet-black-orange) resistors are measuring 60k so I will probably just leave them alone. The 500k (yellow-white-yellow) is reading 880k so it will be replaced also. All the paper caps will get stuffed.
