Does anybody have a BOM list of the components in Audio Research SP-11 and D-115 ???
I have the schematics and can do it myself, but if it's done already I'll appeciate it if someone will share their work.

The problem with the D-115 is worn out tubes and can be fixed easily when I got the money for it.

The more pressing problem at hand is the SP-11.
I have a capacitor in the right channel that goes zzooooooooOOT repeatedly for a minute or so after I turn on the preamp.

Plan A is to replace all capacitors in the SP-11, that's the reason I want a BOM list.

The plan is to use Wifa polypropylene and Nichigon electrolytes.

Other suggestions ???

(A fellow audiophile at work will surley suggest way more expensive components but I try to keep in touch with reality.)
