UHF Modulators

[lnx64]

There's no use in enjoying an antique bulb if I can even use it, besides, the color of the reproduction bulbs are not even the same as the real antique bulbs.

I generally use the bulbs on a dimmer switch anyway and have it down less than half, but sometimes I do have to turn them up so I can see what I'm doing on my desk.

I was thinking about under $100..

How about $80 shipped?

Channel Plus items generally work pretty well in my experience, so this should be a decent unit.

Huh? Are the envelopes of your old bulbs tinted or something? In general there should be no problem matching the color... get the temperature of the filament the same, and the color should match (see "black body" radiation). My repro bulbs (see Amazon link) look quite orange at normal line voltage, and a dimmer control can reduce the temperature more, into to the red region, if desired.

No the glass is not tinted and for some reason though the colors seem to be more yellow than orange

Hmm, I might not be able to afford that one in time.. I took a second look at my bank account, not looking too good.. Otherwise I'd take it.

Also it shows on the back IF in.. Will this even work for my composite video stuff? Not sure how that would even hook up.

You know what? I might get it.. Put it on credit so I can improve my credit score. (I only ever used credit once and I paid it all off on time, but I'd like to keep showing I can pay off things).

I asked them to post the other side to make sure it has the composite inputs, as I saw in another pic that they should, on a bracket with IF out.

EDIT: Ordered.

The IF in jack has an RG-6 or similar cable looped from another jack (maybe IF out?), that is visible in the first picture. Essentially, the unit is two things: The modulator with its fixed-frequency (IF) output, and a variable-frequency ("agile") converter that changes the IF to whatever channel you want to use. These devices can output all of the VHF channels and dozens of cable channels as well as UHF channels up to 550 MHz (so, up to maybe channel 27?).

All of these devices I have seen do have "baseband" (composite video, and audio) inputs. You will probably need to add two RCA-to-F adapters, since the inputs are F connectors also if I remember right.

Ok, I'll get it all hooked up when it arrives. Now, how do I adjust the RF output level, so I can just attach it directly to the UHF terminals on my TV? I'm going to use a UHF channel because I really want to test this TV's UHF tuner too.
