[Radioroslyn]

Have been working on this set for a few days over the last week  or two. Probably the dirtiest chassis I've worked on in a long time. Looks like it was caught in a close dryer lint trap!! After a cursory cleaning it seems that it had seen a fair amount of service work done long ago perhaps in the late '30s. Lots of bakelite blocks bypassed with outside paper caps and a three or four dry electrolytics.

This made for some head scratching as some were not connected in same that the originals were. The 4 section electrolytic had all of it's terminals severed off but I was able to use the top half of the original can and mated it with a newer twist loc bottom section. In the former repair the four section cap was bypassed by using quarter and half mic paper caps. Some terminal strips were added.

Rebuilding the bakelites was compound by the fact that all of the eyelets were filled with solder so had to drill to clean them up so they could except the new caps. According to the Rider's it was missing one of the blocks, above the 80 socket. Must be a different run than the one in Rider's. Also couldn't find the resistor across the shadow meter, this was removed in later runs. While doing the caps measured the resistor to find most were in good shape. Did find one 100K 2w that was 180K. Left it in didn't have one so it's one the when I place an order list.

Powered it up and as per usual it kinda worked. Dial light rubber insulator was shot it got replaced w/a nylon washer of the appropriate size. Was a little surprised to see that the dial lamp and the shadow meter lamp were not connected in parallel at the sockets, six wire in all for it and the sm coil. Times must have been good at Philco! Poor sensitivity so tested the tubes. All tested great except for  3 #78  (rf and if amps) and 2 #77(mixer and 1st audio). Have the 77's sent a note the Bob D for some good used 78's. Got 4 for $15 delivered. 42's look like originals. Popped those in place and worked alot better. With that did the IF alignment which was giving me a problem only to find that I had the generator on the wrong band. Every time I moved the dial on the radio the IF signal would go away DUH!!.

Surprisingly enough the shadow meter is good and works however the dial is worn and  difficult to read so it's going on the order list too. At some point I may pull the aluminum coil covers and transformers to clean and paint them they still pretty grubby.Had it connected to the Eletrolux ant and was picking signal all over. Turned off the modulation on the generator and used it as a bfo to demodulate some ssb and cw signal on the 75m band. All seem to work well. Still have a few issuses to address. Needs dial, grommets for the tuning cap, 100k resistor, 2 speed dial reducer needs a good service.and a good cleaning. Think I'll wait till I get into the two other 116X's till I order.

Chassis is very similar to the 660L. One 116 down two to go!!
