Re: Need some desoldering advice

Here's another idea.....leave them and install new axials on terminal?strips under the chassis.? There is plenty of room to do so.? That's what I did with my PS-500. Pic attached....

My other idea is to just cut the tab on the cap, maybe use a Dremel with cut-off wheel or a big pair of dykes.
If you are replacing the can, just rotate the new one slightly so its tabs are next to the old abandoned ones.

Re: Need some desoldering advice

 

A gas butane torch, even a small one is capable of reaching over 2,000 degs. F. So one of the small pencil tip style butane solder gun/torch units should be easily able to liquify the old solder on the can tabs.??

Re: Need some desoldering advice

 

I find that a Weller gun is all too often not up to the job. The tab and chassis dissi
pate too much heat. In those cases, I use a fairly large American Beauty old fashion soldering iron. They can tranfer much more heat than any gun can.

Pencil iron ?

If so, not tight enough, too loose.

Other (Weller) tips same thing, not tight enough ?

Robert,

I'd try a butane gas soldering iron/torch. That should give you enough heat to get the old solder to flow.

Re: Need some desoldering advice

 

HI Robert

Maybe just not enough thermal mass in tip to properly heat? thermal mass of terminal and wire and solder of big caps?
will it melt solder on smaller terminals ?

Hello everybody, I just entered the group and I'd need your experience and help to fix my FPM300 Mark II.
I purchased it from an experienced ham & tecnician and - beside the added band switch knob that didn't work correctly all the time - the radio was doing pretty good.
After few days it started to lose receiving sensitivity and the rec gain seemed not to work (it basically doesn't raise the sensitivity or really a small amount compared to how it did few days prior), and also the rec audio doesn't raise the volume that much.
Also the transmitter has some serious troubles (and before purchasing we did some nice QSO at the technician QTH) and seems not to transmit since the pre-stages. Finally, the final 6KD6 got fried without turning (for real) the function knob on PTT or VOX modes.
The radio was checked by two experienced technicians but none of them solved the problems. Both of them tried all the realignment procedures but seems they didn't work at all and nothing changes.
I know the situation seems to be very desperate but I really love this rig and I'd do all what is possible to bring it back like it was the first day I switched it on.
Thanks for any suggestion / tip.
Thanks and 73 from Italy - IU4QOC


Re: AM/FM

 

I have one with push buttons beside the dial, pretty sure it is a s-55- the cabinet iis the standard budd
same as on a sx-101a.. I think the tuning mechanism is from a magnavox radio
It is very heavy shipping from 78013 would not be cheap

Craig,

I have an s-40B that I've had for many years, never turned on.? A little cosmetically rough but I believe completely intact, also has a full set of knobs.? Will send it your way if you're willing to pay shipping, which I will determine if you send address.

Also could take pictures but it may be a few days (lots of 'honey-do' things higher on list)

Although the knobs are ok. I am missing the Pitch Control knob. Therefore I am looking for at least it or a full set of knobs.

Is anyone parting one out an S-40B that can sell me a knob or set?

Thanks in advance.

Pete,

At first I thought Hickory Corners was that TV show that Eddie Albert and Zsa Zsa Gabor starred in back in the 70's (hahahhahaha)

Anyway, sure, if that's the way you want to do this.? I will get it off the shelf, dust off, and remove any mouse nests if present (another hahahaha)
Pictures when I can, but before your trip .

Give it a good home....had it so long I don't even remember where/when I got it.

Keep me advised of your travel plans.......I'm right off I-96 at Okemos Road.? MacDonalds or Culvers right there at the corner.

Glad you can use it.
