Also, I suggest to verify at least that the isolator, although hard as rock, is still airtight. If negative, this can be easily fixed with a small quantity of black silicone sealant (the repair will be invisible).
Don't bother about other eBay prices. Had you participated in the bidding, that wouldn't have been the final price. And in any case, as with most things purchased on eBay, that machine has for sure a lot of problems and needs a huge rehaul.

But thanks to the Kab Souvenir VSP (Vintage Signal Processor) most records sound really good, without any bloated bass or overwhelming hiss and crackle. Only when a record has really a lot of rumble, the VSP can't fix it. I have a few acoustic Pathé's that sound like there's a big truck idling in my living room.
I know this device (as said, I've already been a KAB client) but there are some reasons that refrain me from buying it. First of all the dedicated page on KAB's website is terrible and there isn't even a true picture of the product. What the de-hisser, de-crackler and de-rumbler do and how they act is very superficially described (don't even know if all of the three are indeed present). And, also, I really don't like the way in which the equalizer is conceived (with "age" presets), I would like much better a separate bass and treble cutoff control.
But there is also another reason that you may find very weird (but perhaps not so much), and it is that these devices (not only KAB's) are monaural. Although I perfectly know that all 78s are natively monaural, for some reason I like much more to listen to them stereophonically on Hi-Fi systems. I perfectly understand that whatever "stereo" effect I may hear is all due to artifacts of some kind, but still for some reason (psychoacoustics? euphonics?) the sound seems WAY more vivid to my ears. Trumpet especially. If I switch to monaural it all falls down flat.
It may be only me, or not, I don't know. Have you ever listened to 78s in stereo, and if positive, do you perhaps have an opinion on this point?
I'm certainly not too worried about Ebay prices. First of all, that 163 was in the UK, so that means at least a 200 euro markup for shipping. Second, the inside looks pretty bad. The felt is gone, the nickle parts look dull, how the motor is you can't even tell. Also, it is obviously refinished. Mine is also, probably, but this particular one is really light, and they even sanded down the inside of the lid. At least they managed to avoid the decal, but it still looks a bit strange.
About the VSP. I'm not really a technical guy, but I heard the VSP on Rick Conaty's "The Big Broadcast", and also on Radio Dismuke's live Broadcasts on New Years Eve. And I really liked the sound of it.
My 1st turntable I just hooked up to my stereo directly, so I played my 78's in stereo. I know what that sounds like. The music is of course still mono, but the clicks and pops are in stereo. It sounds a bit strange to my ears. But the biggest disadvantage is that when you play 78's directly through your stereo system they are equalized using the RIAA curve. Perfect for most microgroove records, not so good for 78's. RIAA puts too much emphasis on the low frequencies, and represses the highs. For acoustic 78's this is actually not a bad thing, cause there's little at the high end (only hiss), and the low end gets a bit of a boost.
The VSP has:
1) A built-in rumble filter: I have a few records with a lot of rumble, and in my opinion, the KAB-filter isn't very effective on these.
2) A click/pop-supressor (can be turned on or off): Very effective on hairline cracks and works also on scratches, if they're not too deep. It doesn't work on crackle, though.
3) A tunable HI filter: It cuts off everything above a certain threshold: It's a dial, so you can choose how much you want to cut. With really clean records I usually don't use this filter, only on records with a little bit more wear or on acoustics. You can switch between ON and OFF so you can hear immediately if it's just noise you're filtering, or also music.
4) A dynamic noise filter: I'm not really a fan of this one, and I never use it. Basically, the amount of noise that's filtered, depends on how loud the music is. This has an annoying sound effect: the background hiss increases and decreases with the volume of the music, creating a "breathing" noise.
5) A groove wall selector: You can create your own mono mix, by selecting how much of each groove wall you want to use. Especially helpful if one groove wall has more wear than the other, otherwise it's best just to leave the dial at 12 o' clock.
6) A vertical/lateral switch: So you can both play lateral and vertical (Edison's, some Pathé's) records.
7) Several equalisation presets. I understand your desire to make your own combination of turnover and rolloff settings. This is still possible, of course, but then of course you have to put a separate equalizer in the loop. I've asked the owner of KAB if he ever considered to make a VSP with two dials for Turnover and rolloff (like the Esoteric Sound Re-Equalizer), and he had studied the possibilities, but it would end up costing more, and according to his own research most of his customers liked the easy of using presets better.
Before I had the VSP, I also had Esoteric Sounds Re-Equalizer combined with their Surface Noise Reducer, but I wasn't really happy with the results. Using the guidelines from the manual, the background noise increased immensely, and using the surface noise reducer introduced the same "breathing" effect I described earlier.
With the VSP these problems were gone (as long as I don't use the dynamic noise filter), and soon I even began to like the fixed presets. I mostly play 78's from 1920-1930, so I mostly use the AC setting for acoustic, and AE for electric recordings. Sometimes I use a different setting if a record doesn't sound good (not enough bass or highs). There's an extensive list in the manual with suggested presets for the different record labels.
If you want to get a general idea about the results I get, I posted several transfers in the Music section. These sides were all played through the VSP, only thing I did afterwards was give them a pass through Click Repair, to remove the worst crackle (very useful for HMV's or grainy Victors), and some of the clicks/pops the VSP missed.
What I like best about the VSP is that it's easy to use, it's all in real time, and it's all analogue. With digital processing you have the risk of introducing digital artifacts. The only thing that was a bit complicated is that I had to buy a separate power pack here in Europe, to use the VSP with 230V. But the owner of KAB (Kevin) was very helpful with that.
Perhaps I will try to tweak the 5B soundbox a little. Only problem is I can't loosen the lock nuts. Even the smallest wrench I have doesn't fit.
