What Have We Here??

I found this today at a 2nd hand store that deals in estate sales. It's a tubed video booster using one 6AK5 and something else on the left that looks like a tube. It has a single transformer so it boosts something. I can't think of a use for it other than a conversation piece from a bygone era.

That's what I was gonna say, too. It has one set of terminals labeled Antenna (I presume) and the other labeled Rec, which I assume is short-hand for receiver.

Should hook it up to my OTA HD antenna just to see what happens.
 
Hey Archie, if you wanted to get it working, you could always use it to boost FM signal on an old tuner. That would be cool, especially if you were in a fringe area.:yes:
 
I plugged it in using a dim bulb tester with a 40W bulb but not wired to a receiver. All tubes and the indicator light lit up. Maybe the thing actually works. Now to find a receiver to use.

Edit: I wonder if it would work as a mono amp with a source and speaker.
 
Judging from the online picture you found, your two outer knobs are not original ones, but I sure like the look of them!

Cool if you can get this thing to work!

It's probably got an FM trap, doncha think? FM is nestled between (IIRC) the old analog channels 6 and 7 on the old VHF band. EDIT: yup. http://en.wikipedia.org/wiki/Very_high_frequency

Otherwise, it's virtually utterly useless (although a few of the high VHF frequencies are still used in some markets for OTA DTV).

Whaddya mean, remember? Some of us still watch TV (such as it is) for free. :-)

Negatory.

SNIP.

I noticed the dials on the front were split between 6 and 7, so that makes sense. So the question is could this thing be wired into a bypass mode, and used for FM only, that would be cool. The front dials would become useless, but at least it would be useable for something besides a museum piece. (I would take before pix and leave everything bypassed alone, so it could be put back someday if desired...)
 
Not only are the knobs difference but instead of two 6AK5 tubes it has one 6AK5 and one JAN (Tung-Sol) VT269, a not cheap tube.
 
I like the knobs on yours more than the original chicken head knobs. Maybe you can use it as an FM antenna booster on that ancient Fisher mono receiver you have.

yeah it could be used for that but... ive been loooking for a tube one that covers just the fm band from either ev or the many other mfg at the time that that sold fm boosters as well as the tv ones.i see lots of the tv boosters but rarely comew across the ones dedicated to fm

I was thinking using it on something with less potential value than the Fisher FM-90X at first. BTW, that Fisher gives a surprisingly nice mellow, clean, musical sound. I know that's characteristic of tubes but I didn't expect the same musicality from a tubed tuner played through a SS amplifier.
