[Music in a bottle]

I again pulled the chassis from my model 70, to lubricate the controls. Again, I was wondering, aside from the RF coils, how difficult it would be to restore the chassis electrically? I have a good grip on replacing the electrolytics, but is it mandatory or recommended to replace the resistorstoo? What would be the aproximate cost to recap the model 70? Also, Would it be advisable to open up the power transformer for visual inspection or would this be total folley? I finally have a spot cleared to attempt the restoration, but am leary as to whether I should try it or farm it out to the professionals If I do attempt it, I will be sure to put up plenty of pictures, so you all can get a good laugh at the very least!
