Just received your PM, MarioMania.
Unfortunately no, I do not recall ever seeing a VCR with channel 2 modulator output. I have owned, rented, borrowed and resold many, many VHS and BetaMax VCRs since 1980 (more than I can count), but not a single one varied from the channel 3/4 standard modulator. AFAIK, all the '80s Montgomery Wards models were made by Panasonic/Matsushita using the standard 3/4 modulator: if Tulpa is remembering correctly about his parents' Montgomery Ward VCR, the odds of you tracking down that one particular "renegade" 1984 model are slim to none. Aside from one or two oddball items, pretty much every consumer video product since 1975 has used the channel 3/4 modulator.
All of the cheap, affordable, consumer-grade accessory modulators are for channel 3/4. If you absolutely must have channel 2, you'll need to spend more money for a pro or broadcast-grade RF modulator from mfrs like Blonder Tongue. These pro-grade modulators are special-ordered for whichever channel you require. The cheapest Blonder Tongue Channel 2 Modulator costs approx $155 from dealers like this
. Note they do occasionally pop up second hand on eBay for a fraction of that cost: there is one available now
Otherwise you may want to reconsider migrating to a UHF frequency. Reasonably-priced UHF modulators
with variable frequency are available from electronics dealers like MCM for approx $50.
The Sharp modulators you linked to are an obscure specialty product not commonly available as a single unit. That surplus vendor has them priced under $5, but prefers selling to commercial buyers in quantities of 200 or more. Perhaps they will let you have a couple of "samples" if you offer $10 apiece. They look rather tiny and low-powered to me: more of a specialty cable-service part than something suitable for your home system.Edited by CitiBear - 4/12/13 at 5:48pm
