Well that was short lived :lol: One of the HF2000's has decided to go open circuit :rolleyes: Time to upgrade those tweeters to some Seas methinks...Quote:

One of them will be yes... The other working tweeter is mint so I'll be selling that to fund the Seas tweeters + recap. To be honest I already mentally marked the grill "for Martins Gales" :lol:Quote:

Some clever chap over on the diyaudio forums has calculated the necessary crossover circuit for the Seas 19TFF1 to give a well integrated & flat frequency response. This can be achieved whilst keeping the original inductor which is nice... All I have to do is increase the 6uf cap in the HF section to 10uf, add 15R in parallel & 1R in series with the tweeter.
I just need to work out the cosmetics as I don't want a silk dome with plastic faceplate sitting there... Even if its under the grillcloth I'll know its there ! :D
Nice pair of HB1's in need of a refoam http://www.ebay.co.uk/itm/1611150149...84.m1423.l2649
You are a star, James. I already have one grill, so it's only another one that I needed! Taken to PM :)Quote:

I dread to think how it sounds but I do like the design http://www.ebay.co.uk/itm/1960S-PHIL...item19e284cbfa
"Seller refurbished" - I dread to think what it was like prior to the 'restoration' & What Cambridge Audio have to do with it I've no idea, the spec sheet glued to the cabinet says Acoustics Research :doh: :rolleyes:

That would be worth a punt at such a low starting price - the guy clearly doesn't know what they are. The AR 3a sounded bloody good at the time. I think the tweeters were prone to blow so I'd want to know they're working first.
