Henry Tempo One, #2

 This is the 2nd Tempo One I got from my friend, Frank. These are great radios from around 1968-ish. 

I started this restoration by tackling the cosmetic issues. Stripping and repainting the cabinets, soaking and cleaning all knobs, and replacing the incandescent lamps. What a great looking rig!

I did the typical things... cleaned the pc board, clean the tube pins and tube sockets, checked all tubes and replaced as needed, checked and replaced out of tolerance resistors, replaced electrolytic caps, serviced all controls and switches, and gave it a full alignment. The solid state balanced modulator was in serious trouble, and required a rebuild with new semiconductors. 

After restoration, it came online and worked great, and found a place at an operating position in Studio A :-) . 

GU-81M Build...chassis layout...

 In the first post about this, I showed the transformer...always the first and most important part. Here's another pic of the tranny with my hand on it for size comparison. 

This chassis is a steel beast, and it needs to be. This will ultimately be mounted on a shelf in a 19" rolling rack. This was salvaged from a 1952 RCA Majestic TV set. You'll see in the pics below. I'll block some holes, and make other changes, but this Majestic pice will live on! I'm going with 2, maybe 3 GU-81M tubes, to be determined. These tubes are pretty unique, in that they require NO forced air cooling, despite their size and power output! Here's a few pics...

Playing with the tube layout in this beast.

No forced air colling required, and at 3kv, these will approach 2000 pep output, each! I'll use a cabinet blower, just to keep things cool.

Bottom drilled, all parts removed, sanded, and ready to go!

Top side stripped. It also yielded a transformer good for a 300 watt-class amp. 

Old TV chassis with picture tube and other stuff removed. This girl was dirty!

The original RCA Majestic TV console...

GI7B One Tube build...

This is the beginning of a GI7B amp build with a single tube. I picked up the cabinet at a hamfest, it was originally an audio amp for a public address system at a school. I gutted the cabinet, smoothed and sanded it, and applied a black wrinkle finish from VHT. I'm now selecting the transformer, controls, and other components. Stay tuned!

Lafayette KT-200

 This is a Lafayette KT-200 shortwave reciever I found locally. I love these old SW recievers... this kinda looks Hallicrafters S-38-ish...esp the knobs and rx dials. Anyway, here's a few pics, pre-restoration...

Coustic 7009 10-Band Eq

 This is a Coustic Model 7009 10 band equalizer that I got from a friend. It was extremely noisy, due to noisy pushbottons and slide controls. After an intense cleaning and lubrication task, all was well. Great eq! Here's a few pics..
