I've pulled the can and am going to replace with individual caps--perhaps going with a bit larger values than the original. What do you think?

Thanks.



Leadlike,

My, quite a big and fancy bedside...

Yep, first thing I did was replace the SL with a diode and hum is still there. Thanks for the info on the tubes, I looked on that auction site and the 1L6's are outrageous, some are asking $100. I'll look for the 1R5 as you suggest to use during testing. BTW, is this a direct sub for the 1L6?

Thanks.

There was a bad mica in the tuning assembly getting to which required partially disassembling the tuning assembly itself. All in all, one of the less fun recaps I've done, but its a nice radio, will be nicer when I get the alignment touched up.

There is some documentation of your set here:http://www.transoceanic.nostalgiaair.org/
though you may already have all you need.

Another alternative for preserving the expensive 1L6, someone sells an adapter that allows you to use the 1LA6 Loktal tube. Some information here:

Here's an ebay site selling the adapter (no affiliation).http://cgi.ebay.com/1L6-to-1LA6-Adap...94716360272430

Though at least mine still works great after all these years.

But, just to check that the radio is working on the AM band, it works just fine. Not all 1R5s were created equal-some will do several of the shortwave bands, and on the set I just worked on, the 1R5 couldn't do anything above the AM band-just a terrible howl coming from the speaker.

On my set, I put in a locktal tube. I didn't buy or make a conversion socket, I just soldered flying leads onto the tube pins with thick wire, and plugged it in.

My grateful thanks to everybody for your suggestions and comments...

I spent some time with the radio today and added discrete caps (larger values too) to replace the multi-section...and viola, we have lots of stations and absolutely no hum! Isn't that just the "bees knees". I'll probably put the multi-section cap back in just for looks.

BTW, what do you guys use to blacken up the vinyl on your radios if you have any covered with this?
