Has anyone tried to remove the main tuning bezel to clean or repaint it? If so can you tell me the best way ? I would like to atleast wipe it with wd-40 on the inside to get some of the rust off but not get any on the dial. 73

Andy K,

I have been looking at my Super Defiant (SX25). It looks like a person may be able to remove the main bezel by first removing the alunimum shield that the pilot lites mount on. Then turn the tuning gang to max capacity and mark the tuning capacitor shaft and the hub (part that has the set screws)on the scale so they can be aligned again later and sliding the scale back on the shaft out of the way. May have enough room to remove the bezel. You may want to look at yours and study it to see if there could be enough room made for removal. Otherwise I would assume the case would have to be dissambled. Perhaps there are others who have done this or taken the case apart or who have done what you want to. In any case I would be careful around there so not to break the dial or break one of the dial cords which look like it would be fun to restring.

: Hi Radiodoc,Thanks for the response I was wondering if you were the same radiodoc on wbcq shortwave? Anyway I tried moveing the dial back and it doesn't go back more than an inch so it looks as though the shaft doesnt go all the way thru it. I will have to approach it some other way.But any other way looks a litte to involved for my nerves I just picked this up at a hamfest last year It powers up, but when I switch it from standby to receive I smell smoke any ideas? sorry for so many questions . Best Regards ANDY

Hi Andy K,

In answer to your first question, I am not him. I am pretty sure that the electrolytic capacitors in the power supply are bad and will all have to be replaced. The SX25 I have had bad electrolytics and had to be replaced along with the paper capacitors in the other stages. If there is no smell or smoke with the switch in standby position (this opens the high voltage centertap on the power transformer) and the power transformer doesn't get very hot after several minutes, then the power transformer is probably ok. There is a schematic on this site for the SX25 if you need one.

:Radiodoc Hi Radiodoc, How did you replace the electrolytics,did you put them in another can on top of the chassis or just tuck them underneath? I was thinking [if I could get away with it]I would just put them underneath the radio with the other capacitors.

Andy K,

As I recall I had a can electrolytic that had about the correct values and voltage for the HV caps and I used a separate cap underneath for the audio tube cathode bypass. You can leave the old can mounted for looks and install new electrolytics underneath the chassis. Just be sure to isolate the old cap sections from the circuit. Perhaps using an insulated terminal strip to make the connections. You may want to check out http://www.dialcover.com/home.html He has several different multisection electrolytics that he builds.
