Well, I finished up the new 4X1 windows with real 3/16" glass and painted the outside glass border with flat black paint. Looks a whole lot better.  The shop only wanted $8.50 for the two cut glass windows and mirror clips.

I took some shots of the other rigs while I was at it.  Might as well make it a rig tour.. :-)

Maybe some others can do the same thing. It's always fun looking at ham shacks.

We can't forget Mr. Clean,  the 3CX-350J driver for Dr. Love...  This is part of the AB1 low IMD linear amplifier chain.

I received an email wondering about rig covers.....    Yes, of course there are covers to protect from HV contact.  I have a rule that says I should not be able to touch any high or low voltage in the shack with my hand without a lot of effort.  It also has to be protected for cats and dogs. Cats can get into everything.

Here's the modulator and RF deck both with their covers on. I have the RF deck riding on a pedestal with a thrust bearing for access to any part. The whole cover slides off the top in one piece.  The modulator is on the floor with wheels for easy pull out and access to any part. The covers slide off just like the RF deck.  This arrangement is because of the extreme weight of the mod iron and other stuff inside.  Easy servicing is mandatory as we get older.

I chose not to use a rack for Fabio II like Dr. Love (linear) has.  Rico Suave (PDM rig) is somewhat jealous too.

The layer of dust seen in some pics is evident after a 3 year hiatus...

I always chuckle at the names of your rigs.

His fear was when I turned it on for the first time life on earth would come to a stand still.

Thanks for the comments, guys.

I just started the next resurrection... the tube PDM rig using four 4D32s finals and PDM modulated by four 6LF6 sweep tubes. Killer rig! Industrial workhorse kinda rig.

It has been sitting for three years and as luck would have it, the SS PDM generator board is not putting out a pulse. Looks like a bad chip, so I ordered another one.  Why does this happen?

Don't let this modest looking rig fool ya. It will put out 500-600 watts of AM carrier, very heavily modulated. If I had just one rig that sounded the best and was a daily driver... cool in the summer, I would pick this one - Rico Suave, the Dual Quads wonder!  Very efficient; The RF finals are about 82% while the PDM modulator is about 90%. I push them both very hard with grid current and high screen current, especially on the modulators to get the highest audio peaks and efficiency.

Not pictured is the PDM coils filter that I once used on a 4-1000A PDM rig. They  take up about as much room as a wheel barrel and are on the top shelf.

The audio is exquisite... DC to 15 KHz no problem. I was able to work out the minor cross over distortion pretty well over time that is often exhibited by tube PDM rigs. Frank / GFZ gave me some good advice on this rig as it was being built.

BTW, I am a big "fan" of mounting a fan directly above the tubes. The air makes a nice symmetrical pattern and then fans out away from the base.  Good for tubes that are not normally cooled.   Notice the RF deck meters are under Plexiglass. The RF final (and grid / screen supplies) have to be floated for HV in order to PDM series modulate the cathode.

T

** Shown below is the SS PDM generator on the fritz, the PDM modulators and the 4D32 RF finals.  I am a big advocate of 4D32s. They are in the same rugged class as 813s and 4-1000As.  The 2.2KV power supply is not pictured. Yes, 2.2KV peak on the 4D32s under full modulation...  The QIX negative peak limiter is built into the PDM gen board.  

You can see the modulator tubes plate color fluctuate at 2 cycles. This rig makes shark fins on the scope. This is a pattern reserved mostly for SS PDM rigs...  :-)

Yep, almost forgot about the GTO Blue receiver, John -  translucent blue lacquer rubbed out using a silver base that shines thru the blue, acting like a mirror.  I once painted a car using the same technique.  Just like your dog's hat... :-)

This receiver was built originally in 1972 and was one of my first ever homebrew projects.  I took the panel and in ~1995? built a new receiver. That's original lettering and paint. Back in 1972 I built my own "S" line using those  Bud shadow cabinets consisting of a receiver, ssb/AM/CW transmitter, a pair of 813s linear and a station master control box with tube CW keyer. Complete HB station from VFO to antenna and back. Only the RX front panel remains of that original station.

The new receiver version is an 11 tube superhet with AGC, and three IF stages and one RF. It uses a pair of p-p 6AQ5 audio outputs. Totally self-contained. I also tap the diode detector into a stereo amp for hi-fi audio. The VFO tuning is like velvet after some extra work. Wound my own RF, mixer, VFO coils.  There is plenty of shielding underneath which was needed due to the high gain. All the orange wire is Teflon shielded mini cable. It has a BFO and bandswitching. This was one rig that surely took as much time to get running perfectly as it took to build. I borrowed many circuits from the handbooks as well as used a couple I designed.  The original was my only receiver for about 5 years until I acquired an R-390.

It still works FB and is on the shelf. I really should get it online again.  I mean WTF.

That's awesome! With those Isotrons on there you can barely see it! I'm going to forward this picture on to my HOA to see if it'll fly.
