That woman who's holding the PC-3 wants to watch out for that low flying balloon!
The PC-B7 speakers - with tweeters - were available as optional extras for use with the PC-5 but I've never met a PC-7 which is, as far as I can tell from the image in that pamphlet, neither more nor less than a PC-5 with an added mixer under the A/F amplifier.
It also appears to have the same number of DC in/out connections as the PC-5, suggesting that the mixer is passive unless they stuffed some extra battery space in there, or supplied a Y lead for connecting a DC supply from the deck.
I am not even sure if JVC PC-7 existed at all.
It wouldn't matter as much as it does with, for example, an M90 since the tuner module and cassette deck from a PC-5 appear to be exactly the same which in turn means that anyone wanting a longer VHF spread and/or LW coverage only has to pick up a broken PC-5 from eBay (they're stupidly cheap) and substitute the JVC components into the Victor.
All I know is that I have been looking for the PC-B7 speakers for my PC-5 as I'm collecting all of the accessories to go with it and already have the nylon holdall and a remote control is winging its way to me as I type this. The stock PC-B5Ks are remarkably good but I have had the little JVC connected to a pair of Wharfedale Delta 50s and couldn't believe just how much more deep bass could be squeezed out of that tiny (array of) box(es).
I already spend far too long looking at the pictures on the Russian audio site, it's a brilliant resource.
