Aleph 3
 
Obviously my Aleph 3 runs very hot, but i did notice a little burning smell. I have removed the top cover and it does have some discoloured wires from the heat.... but it does not look like everyone elses Aleph 3. The powersupply caps are not the expected large caps but two banks of 24 small caps. What gives? Does anyone know of an Aleph 3 like this? Also the wiring is untidy and there is insulation tape in places!!

That looks like cotton jackets on the wires.

is this a Pass made one that's been modified?
I only ask as the heat sinks are like I saw at a HiFi doo and only knew the amp as being a Pass amp

obviously tweakers work , on wrong side of competence ;

just look at Graetz made of zillion diodes in parallel

simply put - if those are cotton sleeves , that's snake in bed = possible fire in house

that poor bstrd begs for rework

I bought it used on Ebay so i assume it has been modified and yes cotton insulation....it looks horrific. It does sound rather good however but considering i have not heard it in its original state its kind of bugging me to reinstate it. What would be the benefit of having many smaller caps as opposed to the standard set up?

if caps are good (can you see what type/manufacture are those ? ) , less total ESR - means lower ripple and higher current reserve

but - they need to be cleverly wired , to achieve full potential

in any case - send it to someone who knows his drek , to rewire it completely , change that bridge etc
