VERY and oh yes! I put more of the same caps in my pre-amp and that too gave good results, but not as dramatic as in the Alpha. The resistor shorting was probably important too! Never mind the extra filtering, it clearly hurts the sound.

Cor - that's it then - I'm off downstairs to rip it all open again - sh.. the wife will kill me - I've already lost two hours doing something else to it today - pah !!!

I've no room at all inside the box so I'm going to have to bolt the caps to the back panel for now.
It won't hurt doing that - and you just proved it - how glad am I ?

Pics already printed off........bye...........

Oh dear, look what assembled itself on the kitchen table... it appears to be some kind of über-cap made from 20 x 470uF/35V Elna Silmics

I've not decided exactly, I just felt like doing it to use up some caps which are just old pulls. I might use it for smoothing my digital filter power supply, or the decoder, everything else has decent modern caps or is in the player where space is limited. This will be going off-board. Should only be about 9400uF, but the impedance will be pretty low with it being 20 caps in parallel.

Well, after all the excitement of the big caps job you did I dashed off to do my version, albeit with 2 half decent 6800 uf caps - they will fit perfectly where the 6 x 1000's were.

Stripped it down, did the links as you described and found I didn't have enough solder to finish it off !!

I can't use the exact words here - but you can probably guess.

So, tomorrow it is then

So that's the benefit of lots of small caps - low impedance, thanks.
Fancy having 20 Silmics as ' old pulls ' !!
Outrageous

Haha, if only. They are old pulls but I bought them in a big bag from Ebay. I've modded a few CD players but not THAT many.

Fancy running out of solder at that exact moment! I also ran out of my normal solder this evening - super solder. Very annoying.

Gees, not much leaded solder left on Ebay. I don't know where we're going to get it from in the future, lead-free is not an option for DIY.

Agree - and lead free IS awful.

We both ran out ? Weird

63 - 37 is my thing, think it has rosin in it too - very low melt temp and runs easy into the nooks.

Not heard of super solder - is this one of Leo's ?
I'll look out for that
