Jul 20, 2006. Place for any discussions not related to Buying, Selling and Trading ham gear. Seems to be doing what the manual calls for, however I have a friend that. You've provided some information on your Tempo 2006A 6 meter RF. Henry Radio had to stop manufacturing the 6N2 because it did not meet.
It came to market as the Henry Tempo 2000; Id never even seen one before. I had one in here for service with a fried PS and called Henry with a question. The tech said it was bought as a close-out from Johnson in 1971 and no one there had any experience with it.
They were all retired or dead is what he said! Still has the original 3-400Z's. It is also a royal PITA to service as its all put together in layers. Luckily I had a good plate transformer on the shelf (impulse buy at a low price) otherwise the customer would have had to bend over for a Dahl at some outlandish price. If anybody has one please realize that for 120V operation it has the neutral and ground leads tied together, a big NEC no-no. I dont know if that was a Johnson or Henry gaffe but thats the way it arrived here and shows in the manual. Carl KM1H Title: Re: Trivia question Post by: WZ1M on July 20, 2009, 12:44:51 PM.

Carl KM1H I don't have the Thunderbolt or 6N2 Thunderbolt schematics handy at the moment, but I thought they tied the ground and neutral together for 120 volt operation on those amplifiers.
Besides being called a Tempo 2000, Henry initially had a product brochure that called it the T-2000 and the K-2000. K-2000 might have been for the export market. Title: Re: Trivia question Post by: Pete, WA2CWA on July 20, 2009, 01:42:33 PM. Carl and Gary - Thanks for the updates.

Actually, if we all look back over the last 50 to 60 years, we can probably find a number of one-hit wonders that came from manufacturers that targeted the amateur market. Some actually saw the light of day, even if it was brief, whereas others never saw the light. And, of course, we probably know, as this sign points out: (Title: Re: Trivia question Post by: WQ9E on July 20, 2009, 01:48:45 PM.

I dont know if that was a Johnson or Henry gaffe but thats the way it arrived here and shows in the manual. Carl KM1H Carl, A common bad practice with Johnson. The Desk KW is also set up with ground/neutral tied together along with most of the other high power Johnson gear running on 240 volts; I guess that was the way things were done in the 50's. I am distrustful enough of the vintage gear switches, etc. That I have a separate panel connected through a 60 amp shutoff switch that provides power to my radio gear and when I am not using it the switch is off. There is a lot of potential for trouble with these rigs including aged switches, bypass caps on the line side of the fuse, etc. Rodger WQ9E Title: Re: Trivia question Post by: KM1H on July 20, 2009, 04:07:40 PM.
Carl, I built my HB amp with a 4 contact plug to avoid having to do the same thing with my blower. I have a feeling few radio rooms would pass a close inspection from an NEC inspector. But the worst mess I have ever seen was a nice older home my sister-in-law used to own.
I was tracing an outlet problem for her in the basement finished by the previous owner and found the outlet had about 6 feet of proper 12-2 w/ground attached and then it transitioned to three different sections of lamp cord using duct tape around the twisted (no wire nuts) splices for the remaining 20 feet back to the breaker panel. About a year later she called after one of her visiting college friends (who was a bit 'light in the loafers') kept shocking himself by touching the metal light switch plate while standing on the concrete floor.
He was only too happy to demonstrate when I got there; apparently some types really do find electrical shocks enjoyable. Rodger WQ9E Title: Re: Trivia question Post by: The Slab Bacon on July 21, 2009, 07:38:34 AM.
Could be this; the Hallicrafters SX-112: (Pete, Are you sure they were never produced?? I remember seeing what I thought was 2 of them at the Howard County fester in West Friendship a few years ago. This tailgater had 2 of them, unfortunately they were both in really bad shape. Both had been badly cat-pissed with very rusty chassis's. And both of them had cracked or broken dial glasses.
If one of them would have had a good dial glass I would have probably took the gamble to buy both of them in hopes of making 1 good one. I thought they were pretty cool looking radios. They didnt make that many models of the 'big box' radios with slide rule dials. IIRC it was only the SX62 and the 101 series.
The 2 that I saw at the fester looked just like the one in this picture. Now it kinda makes me wish I had bought one or both just for a conversation piece!! The Slab Bacon Title: Re: Trivia question Post by: ka3zlr on July 21, 2009, 07:54:20 AM. Hey Johnny, do you remember where you saw the Avenger?
It's been probably a decade or more now, but I'm pretty sure one showed up at Hosstraders when they were still having it up at Rochester NH in the late 90s. There was quite a hubbub about it at the time due to its scarcity.
Didn't see it myself, probably too busy drooling over Big Al's radio shelter with the functioning ART-13 complete with dynamotor. Everytime he keyed the mic it said 'weeeeEEEEEEEEEEeeeee'.

The Slab Bacon Well, we know they made one or this picture would have been difficult to take. I believe only three prototypes were built.
None went into production. Slide-rule dials, 'big-box radios' from Hallicrafters probably include S-47, S-108, S-129, SX-62, SX-71, SX-101, SX-110, SX-111, SX-130, SX-133, SX-146. There were also a number of smaller/lighter weight slide-rule dial radios from Hallicrafters.
Title: Re: Trivia question Post by: w3jn on July 21, 2009, 07:01:00 PM. Hey Johnny, do you remember where you saw the Avenger? That probably would have been 1998 or 1999, at W3HM's with HUZ and N9MC on our way to Dayton. Back when I was in college in Mankato, MN (about 30 mi west of Waseca), EFJ used to hold mini-hamfests and the EFJ radio club would sell off boxes of their prototypes, engineering mockups, etc.
I got one of the first cellphones ever; it was EFJ's prototype for service testing in Chicago and Dallas (according to the labels on the EPROMs). It was the size of a Motorola Micor and the control head was just a hanger-upper for the handset with a couple of pushbuttons on it. I ended up tossing it when I moved to DC, but I wonder what other cool stuff ended up with hams in teh southern MN area.
EFJ stuff was.very. popular in MN, and no mid-80s hamfest was complete without a couple people tossing Viking IIs, Valiants, etc in the dumpster (I once saw someone heft a 500 into the dumpster - I remember the PS/modulator maded a spectacular crash as it smashed thru the top of the RF unit). Course back then the stuff was the object of much disdain, there being.no.
AM activity in MN that I ever heard back then. Title: Re: Trivia question Post by: K1ZJH on July 21, 2009, 07:41:46 PM.

I'll have to dig out 'the book' when I get home tonight and try and figger out what they were!
The 1000 is way friggin kool!! It would be neat if they would have gotten into production!

That's the way the Gates BC1-T is set up. I separated the neutral from the ground in mine.
I think other broadcast transmitters were wired the same way. EFJ stuff was.very. popular in MN, and no mid-80s hamfest was complete without a couple people tossing Viking IIs, Valiants, etc in the dumpster (I once saw someone heft a 500 into the dumpster - I remember the PS/modulator maded a spectacular crash as it smashed thru the top of the RF unit).

Somebody had to have been pretty damned stupid. Did anyone dumpster-dive and retrieve it?
I recall that attitude being prevalent during the late 60's and throughout the early to mid 70's. I was derided many times at hamfests by others as they watched me haul things like plate transformers, oil capacitors, modulation transformers, black wrinkle panels and chassis bases, large transmitting triodes, etc. To the vehicle. But by the mid-80's, that kind of stuff was once again fetching real money at most of the hamfests I attended. To this day, I feel disdain for the term 'boatanchor'. However, I got in the last laugh, buying all those items for pennies on the dollar, seeing what people are willing to pay to-day and what audiophools are shelling out for big triodes these days.

Don, As the old saying goes, 'He who laughs last, laughs best' and you certainly got the last laugh with your grabbing soon to be valuable 'trash'. I am glad you saved so much of the good stuff.

Hey, how many of you have a Hammarlund HR-10 receiver? (Title: Re: Trivia question Post by: Todd, KA1KAQ on July 23, 2009, 08:59:10 PM.
