  I know this has been covered in the past, and the Telepost LP100 highly spoken of, but I just wanted to add another thumbs-up for this device. My shack's measurement repertoire has always included the standard offerings from Diamond and Daiwa, in their pseudo peak-reading versions, which are quite decent devices in their own right but fall way short of delivering true peak-reading performance. Actually, the best peak-reading analog wattmeter I've used is an old Mirage MP2, but it's a VHF device, 50 to 200mhz.
  At nearly every hamfest over the past few years, I've found myself looking at used Bird 43's—some very nice looking and for decent prices; others looking like they'd been dragged to the 'fest on a rope behind the seller's vehicle. Often there are no slugs included—or at least not the slugs I'd need—or sometimes the meter is being sold only as a package deal with a plethora of slugs, none of which would suit me.
  Brand-new Bird 43's are an option, as are the Coaxial Dynamics offerings, but with slugs and the peak-reading kit, you're getting into some bucks; all for what consensus seems to indicate would be dubious peak-reading performance. For steady carrier readings, my Diamonds and Daiwas are close enough. Array Solutions used to offer the PowerMaster, which was well reviewed, but I believe they were made in Ukraine, and the war pretty much ended that.
  So, in part because my recent acquisition of the K7DYY Super Senior has had me paying more attention to my PEP, I ordered myself an LP100A, and I couldn't be more pleased with it. For around $500, you get an accurate peak-reading digital meter that doesn't require the purchase of slugs or pickups—it comes with a 3KW pickup—and will do other tricks besides reading RF power. You can also download free software to display the information on your computer screen, which is great for me, since my usual operating position isn't in front of the rigs but in front of my computer screen, on which is also displayed the SdrUno screen, the REA Steve-O-Meter, and often a webSDR.
  This meter is one of the best radio accessories that I've ever purchased!

I have 2 complete but un-restored BC-669's that need to find new homes.  Both are complete but it should be assumed these will need restoration.  
I can bring both pieces to NEAR-Fest is anyone wants both of these.

Pictures on request.....

The original DX-60 used dual filament windings, one fed the DX-60 and the other was brought out to the VFO socket.  Maybe they used the leftover transformers in the early A model production.

One side of each of the separate windings is grounded in the DX-60 so I guess you could call it an external center tap Smiley

Wow. So sorry to hear this. Talked to Brandon quite a few time on 40 meter and a few times on 75 in the past. Gone too soon.  Cry

Full rack discount, $1500

All are sold as-is. I've done no operational checks.

I can deliver to Maryland. Will not ship.

Very Nice R390A
Smooth, tight controls & switches..
Was my brother's who is now SK. Seems to work fine across the spectrum.

Too heavy to ship. Pick up/meet up within reasonable distance of Hamilton/Cincinnati Ohio.

Can also meet @ Hamvention.


$600 or trade for mobile size HF (yaesu 857d, 897d, icom 735, 706, alinco etc.) rig.

"Well I broke out my VOM and did some investigating. Here is what I found, the following wires have continuity, voltages are unloaded:
Black wires pair, primaries.
Red wires pair, 260vac.
Brown wires pair, 110vac.
Yellow/Y-G pair, 7vac.
Blue/Y-B pair, 7vac.

Now in the schematic, the windings for the filament voltage are center tapped, one half 6.3vac is used for the filaments while the other side goes, also 6.3vac goes to the accessory socket of the DX-60A.

So I'm going to assume this is either a replacement transformer or a difference between the schematic and what's real.

So I think that clears things up, I'll just have an extra set of filament lines hanging."

I'd say you are on to something useful Dan.
