The schematic for the model 87 can be found here, it even has a layout of that potted condenser can: http://www.philcoradio.com/tech/images/87.jpg
I'm not sure whether that can has a terminal strip or not, if it does then it will make life much easier. I really wish people would quit pinching the used #45 tubes out of these sets, someone at some point has to drill it into the heads of these stupid audiophools that amplifiers are based on science and not black magic and they are not going to get hi fidelity sound out of a set worn, used pair, of 70+ year old triodes. In any event you can find another used pair of #45s (likely st style) or substitute a pair of 1619s in their place with adapters.
