Well, I went looking for either a case for my model 70 chassis or a chassis for my 18b case and wound up finding someone not too far from me who was selling a complete model 70 for a good price. I think I'm going to work on this first while I continue to look for an original chassis for my 18b.
I also had a question. I am new to radio restoration, and I think from reading comments on the phorum that the first thing I should do is probably replace the caps. I was comparing this chassis (pic attached) with my other model 70 chassis, and I noticed that one of the Bakelite capacitors is different. According to the specs sheets I have, the model 70 should have a Bakelite capacitor with number 3903-J installed. The chassis currently in my 18B does have this, but the Model 70 that I just bought has a 3903-L (see picture with the arrow). This block also has what looks like a capacitor soldered onto the outside of it.
Has anyone seen this before? Everything else on the in the chassis seems to match up with the early Model 70 receivers.
