    So how's it all sounding then, Jamie? Could you outline what the sonic improvements you perceive are from the re-cap?

    Well ive been listening to these for a week now after the recap.
    They have benefited mostly in the mid frequency ,as Ken wrote in his thread obtaining the cap value of 24uf using Mundorf lytics and a 1uf Ansar poly has really improved the sound .im listening to Rumers cd Seasons of my soul and her voice sounds so silky smooth and rich,the accompanying piano is also very realistic,id say it was worth all the hard work for this alone.

    Now here's the rub,the HF2000's now seem distance,they are there but its like having a thin veil over the tweeters,not how i remember them,the original tweeters were changed as one measured 5ohms,the other 9.8!
    the spare pair i have and fitted both measure 5ohms.

    Now either the Ansar polys for the tweeters need some time to burn in or the old caps were so out of spec they reduced the output for the mid? can this happen?
    They do seem to be getting better or maybe im getting used to them,or they are fine and this is how they are meant to sound?
    Your thoughts gentleman please!

    Interesting... Having owned these speakers before, sonically I certainly couldn't detect any issues with the tweeters being out of spec (even though obviously they were), as you've measured them, nor did they sound in any way 'veiled' - quite the opposite, actually!

    Therefore, it might be an idea at some point to put the original HF2000s back in, out of spec or not, using them with the new upgraded caps, and see what that does.

    Thats my first job on Saturday! lol if only to put my mind at rest.

    we also between us didn't notice that 1 crossover had a mid range cap value of 30uf and the other 24!
    they still sounded sweet as!

    im sure its just me not being used to the sound now they are back in spec,i will know for sure once my TT is back in action and i listen to some floyd

    Lol - too right... That's the trouble though with making too many changes at once. I've been guilty of it before, too. In hindsight, it would've been better to have fitted the new tweeters after the cap changes, in order to reduce the number of variables from your upgrades, but shit happens!

    Anyway, let us know how you get on when reverting back to the original tweeters.

    I don't know how Celestion selected the individual components when building their speakers but when I worked for Harbeth each driver was tested and measured to conform with the design parameters and each crossover was made to suit each driver, the slight variances in the drivers compensated for with higher or lower component values on the crossover.
    Maybe that is why there were differences with the 66's crossover parts.
    Bloody hell!, that almost sounds intelligent

    Mmm... I guess that's entirely possible [good call], but also remember that the original spec of electrical components drifts after time, so when you're talking about 40-year old speakers, stuff deteriorating/going out of spec with age is hardly surprising.
