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
Its not the receiver that's noisy - its the normal background noise at my location(!). I have found that an active loop antenna works best here, but there is still a lot of noise from things in the house (LED lights, wall wart power supplies etc) and external (smart meter etc).
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/
Old radios have some kind of magic! I admire your skills and ability to find parts for old radio.
Thanks! - and yes, they have 'magic' to me too...

Красивый аппарат! 👍

Thanks Jeffrey. Good luck with the SX-101 - sounds an interesting project.

IF transformers are always fun to take apart! @@jeffreyyoung4104
that's a really nice looking receiver you got there!
Thanks. Its a really classis design - especially with that large and very clearly-marked (and colourful) half-moon dial!
Gerry, what color is exactly the front panel? The light in the room doesn’t permit to see it clearly. Is it Olive drab green?

I wonder if National Radio hand anything to do with that catacomb design? Lovely receiver!

Sounds like too noisy. Is it normal for this model or old tubes?

Very nice radio, love it 😊😊
Yes, they are a bit of a 'Canadian Classic' and certainly look thepart as a comms set

ขอบคุณมากครับกับสาระดีๆ
Glad you found this video useful
I have one as well Its a CSR5A 110930-AZ Spec 106945. I have re-capped it and it works well. Had to build up a power supply of course. VE6CJC :)
Hi Keith - sounds good! - these are very reliable sets.
Красивое радио )))
