LOL I showed some mylars in one of my videos that looked like that...

Funny how some folks interpret what other folks say. Here is Mikes video that snake is complaining about.

That is doable. In fact Mike (Mikes Radio Repair) recently did this to a Browning. He has a video on YouTube.

I do find that a lot in some old gear. But does not hurt to replace these caps since they are hitting 40 years old.

These are great units when they are working properly. I have repaired dozens of them over the years. It has many more features over the B&K 2040/1040 counter part. Again it was aimed for strictly cb repair. I really liked the IF generator, crystal tester and built in frequency count along with...

Thanks Brett, I have found the D104 does work pretty good with the 101's. I have used amplified and non amplified ones. Sorry to hear about the broken heel. Hope that gets better for you soon so you can get back in radio. Yep, we are ok, I had about 6 grand in damage due to wind. lost part...

These are great radios. In fact I am doing a Yaesu FT--101 series on YouTube since I own 5 of these radios. Will end up being 15 to 20 videos. Craig deoxit and IPA is the best cleaners to use on the edge connectors. Those old Mylar style capacitors soak up moister over the years and the shell...

You will probably be ok this time. Like someone else said use a dummy plug in the mic jack if needed.

The best thing to do is never input power of any level into a 8640b. It is not a transmit tester to begin with. Although right on the front of the SG there is a tag that say 50 watts input MAXIMUM. And it is only there to help prevent a problem if you accidently key the radio into it.

Thank you. Yes I am planning on doing that in a "Shop Talk" video one of these days. I need to get online and find another Royce radio to sacrifice a PLL can from.

Desk top speakers from a PC works great

From my good friend Lazarus, 40 ch Royce like the 625 for example. Remove the PLL can or "sardine can" as a few like to call it. Put it in a box and wire it up, Build an attenuator and you have it. just need to ass a audio source.

Signal tracer is a very simple device. An amplified speaker with a probe coupled to it will work. Radio Shack made a "mini amplified speaker" that I have used many times. Google DIY signal tracer and you will see just how easy they are to build...

No Royce does not make a signal generator. "They" being the PLL cans from a Royce radio makes a good cheap signal generator. That is if you know how to modify one of them.

Another episode of Shop Talk. A look at the FT-101, Ghost hunting a TS-120, Couple of nostalgia Radio Shack items, camera thoughts,

#68 Yaesu FT-747 No receive diagnose and repair In this video we have a look at why a FT-747 has no receive on any band. After the repair we find that SSB has distorted sound and then we inspect for the cause.

Why not post a picture of your board

Nope, I have 2 148's from the late 70's. The picture I posted is right out of the 197X manual.

TP-14 is pin 7 of IC3. It is a AN612 single inline package chip.

I do not understand the reason in this.......
