Nice job as usual. I'm about to start on one of mine and was surprised to see so many parts needing replacement. I did keep two sets, a 5 and 5A plus a VP3. Winter project.
Hi Bruce - good to hear from you. Hope you are still doing ok in the UK! Unfortunately, in my experience, most of the resistors in these sets have drifted significantly and for long-term reliability/optimal performance should be replaced (as well as the capacitors). You could 'get away' with a recap and only replacing open circuit and a handful of 'critical' resistors for the set to run reasonably well if its for your own use and you can carry out ad-hoc repairs as and when needed, but most of my refurbishing work is for other folks and I prefer not to have to revisit the sets(!)
What a beautiful receiver! Great job restoring it sir! I love those older radios myself, and I am rebuilding a Hallicrafters SX-101/a as well as the HT-32 transmitter. The SX-101 series originally had 160 meters, and the A had a 2/6 meter conversion band scale, with the loss of 160 meters, so I rebuilt the Mark III chassis with the A circuits added.
@@RadioRestoration Well, as long as my progress is positive, it looks good. Sad to say, I broke an IF transformer, but I have a spare! But I have to tear into it!
Its greyish drab green wrinkle that has some brownish staining here and there. Its unusual for a CSR-5 - other's I have worked on (five I think) have been shades of semi-gloss medium grey with either white or black lettering
The National Radio Co. developed the 'catacomb' design to address the inconvenience of having plug-in coil packs as in the National HRO receiver, yet retain the advantages those had over the more usual band change arrangements of coils selected by a rotary switch, eg. frequency stability and isolation between stages
Good job. I restored a couple of CSR-5 receivers, some had mechanical problems. I have 5 in my collection. There is a nice run-down on these, on the website dedicated to the history and products of the Canadian Marconi Co. I'm also working on restoring a RCN CM-11 transmitter that also has a CSR-5 in the same cabinet. As you may know, the CSR-5 was designed and built for the Royal Canadian Navy, and was used from late WW2 until the mid-1950's.
Thanks! - Yes, Jerry Proc's website is a very valuable resource for the CMC. I have restored several CSR-5 sets and some CM-11 rigs. If you are on Facebook, check out my 'Radio Restoration' blog. Also, there are several of my articles, including on the CSR-5 and CM-11 on the SPARC radio museum website, here: sparcradio.ca/radio-matters/restoration-projects/
