To remove cable ground loop hum: VIEWSONICS VSIS-EU CABLE TV GROUND LOOP ISOLATOR $5.50 on eBay in June 2010 - works perfect and best of all its not in the audio signal path and it is a LOT cheaper than some "audiophile blah blah" stuff.

Very nice job! One question: Where are the Vishay bypass caps available (without having to buy a thousand ;) )?

Hello Kent

Yeah, I know what you mean. I ended up buying a thousand.....!

Just kidding. I bought 10 pieces from rs-components in the UK (www.rs-components.com). The 10 caps cost me GBP16 incl postage and taxes. It took a lot of calling and searching to find a suitable vendor.

Of course, I still have a few left. If you like, I'll sell you for the same price GBP1.60 each plus postage. Let me know how many you need. I probably have 5 left - I seemed to remember losing one.

Just e-mail me. I live in Stockholm, Sweden.

Regards, Kunjan.

Thanks Kunjan, but I don't think that's very practical. I'm in the USA. But thanks for the offer.

Well, almost 5 years later. A friend just gave me a pair of 94-Si's. Kunjan's write-up should come in handy. Maybe I'll hijack this thread and post photos of my refurb project.

 

Any comments/suggestions/advice welcome. The plan so far is to replace the electrolytic caps (5uF & 40uF) with film, replace the spring clip speaker terminals with binding posts, add some internal bracing. I don't like the "sock" grilles but they're not too bad--just a couple of worn spots.

Interesting timing on this. I have my eyes on a pair of these for pretty short money. I will keep an eye on this thread, or new thread Kent may create with interest. At this point, no advice, but comment would be go for it and please post every step of the way.
