Sold the last of my mobile Amps 2 years ago on flea-Bay. The Fat-Boy I had was. 2 x 2SC2290 Tosh driving 4 x 2SC2879A Tosh. I replaced 1x 2SC2290 with the last Tosh I had. Surprised. Was bid up to 483.00. Another much older 6 pill. Higher parts count. 2 x SD1446 driving 4 x 2SC2879 Tosh...

Thank you Nomad for this information. I always wondered what the purpose of the choke connected across the "load variable in my Ken-rich Eagle 500 & 525 ? I just get a similar part as in the Eagle ? Inductance wise/current rating ? 15-20 years ago . Worked on a 515. Showed my friend. Why...

Hmm 53 year old Amp. Did not get to a improved bias today or dc supply hook up. Had to clean & adjust one of the 110vdc relays. Clean & align the main load air variable to stop rubbing & arcing. But discovered something. I removed the cheap purple hook up wire between the input to the...

Hmm. Personally I would not sand. Have a bunch of Rust Buckets. I use this. Rust Reformer

Looks nice & clean. How about a couple of Photos of the inside Top & bottom ? Best PuppetMaster

Thank you the information. Lot of work to build that Amp. Interestingly. Only 350W on 10 meters. The cathode bias resistor value 39 ohms. I have seen this value for audio tube Amps with multiple output tubes. Bear in mind. The Amp in the link requires up to 100 watts of drive ...

Is this amp the POW KW+ ? Or is it the Maco 2 piece. I have 2 POW KW+. One with original but new M-2057. The other I re-tubed to 35LR6 about 13 years ago. I also have the 2 piece Maco. On a RMS reading average Coaxial Dynamics RF Directional Watt Meter (bird 1KW element) The M-2057 tubed POW...

Obviously little interest in re-tubing Phantom's. The best thing for me when hours are piling up and the gadget still does not work. Is to put it away for 10 days. I realized a huge mistake a few days ago. The bridge rectifier I was using is too small. Ohm's law. Watts not Amps. I used a...

Okay I am off today. No handy man work. Have to do laundry ? Ah do it tonight. Back to the Phantom. Clearly major diferences between the tube key up version with 110v DC relays and the PNP key up version. Well. Those Pink wires. What a Hassle. Will fallow them from the High low power switch &...

"Interesting" ....................Well I drive the Skipper 300 in my car with a Tea-Berry stalker 202 base mobile rig. Turner + 3 desktop mic. Prior to the TB Cobra 139XLR, Trc457 then Trc458. Today going to remove from a Trc449 mobile the Digi Scan UFO. Put it on my TB ! All the other bases...

It is a nice Amp. On my Co-Axial Dynamics Watt meter with a bird slug it shows 300-310 watts RMS with very strong 6LF6's. The Dummy load is at exactly 50 ohms. Baby it.6LF6 are not cheap and appear to be very hard to get. Driver CB is set at 2.5W RMS dead key. It peaks to 4W RMS. I keep it on a...

You have to replace the 2N2905 Transistor. While you do that. might as well refurb it. Kit is listed on Ebay for first and second generation Skippers. Great amp. I have run one in my car for years. I use a 3000W pure sine wave invert-er ! Best John

Woke up this morning with a Eureka geezer moment. Try putting the little tube from the D&A warrior into the 31LQ6 Phantom ? Will post back.

Hi, It was laying around for years without tubes except the little tube for the key Up circuit. Ah over a decade ago re-tubed to 24LQ6 3 Phantoms with 12volt relays & PNP TO-220 high side transistor switch. regulated DC 24v filaments. Perhaps pre-Alzheimers. forgot a lot of tube theory...

I use Sprauge audio caps in the 858. -Worth it-. A re-conditioned Turner 3 into an UPD858 SSB radio that has been tuned a bit. They have a built in ; a Clipper. Is as good as you can get on AM or SSB. at 3000HZ band-with. I regularly without asking get glowing reports on SSB Skip. Or "What HF...

Great information: Thanks. Shoosh was wondering LOL. I have been toying for a couple of years with an idea to assemble a Mic compressor fallowed by a Clipper AKA PC196 board or even AKA Lou Franklins board.. Turner board copy might be the ticket or Knight compressor copy. Hopefully I have both...

Well Well. I am having a hard time finding the Data for this FET. 2N3219 comes up in a Google search as an NPN BJT Transistor. Is it possible it is a JFET 2N3819 ? The reason I ask is that I have 3 Turner + 3 with issues. By substitution using Clips verified the Mic Elements are Ok. They...

Thanks 399. Makes sense. Well next project. After recapping a Teaberry Stalker 202. will go back to this Trc457. Just finished a Cobra 139 XLR re-cap. top tier caps mostly Japanese. Very interesting. I have acquired slowly 139XLR, Madison 858, Washington 858, Trc 457,458 Robyn 520D Sams Photo...
