Radiola 60 w/ 103 Speaker
#2

I finally finished the Radiola 60 and 103 speaker and delivered it back to the museum today.  The cabinet came out nicely.

As did the new grill cloth on the speaker:

Here it is back at its home:

The chassis restoration went pretty smoothly, the most difficult was to get the filter box apart.  There is a fiber board cover over the lugs that came off easily but the frame that the connecting lugs are on took a little heat gun action to loosen it followed by clipping the cap connections to it would all pull away.  You should be sure to unsolder the choke leads that are also in this can because you need to retain that.  Here are some photos of the various steps of getting the old caps out and putting the new ones in.  I also had to make a wood frame to hold things in place, although you could also fill the can with wax to do the same thing.

The bypass caps were also replaced but were much easier to get to.

Unfortunately the large wirewound resistor failed so I replaced it with two 10 watt wirewound resistors in parallel.  Overkill but hopefully cooler.  I’m sure that sometime in the future it will need a visit to the shop, maybe I’ll be able to rewind it then.  A fuse was also added in line with the power cord.
