ripping old gear can be cool... i wouldn't say no to some DBX202's!
i'm not sure if i would like capacitors from an old tv in my diypreamps dough.
one of the reasons i like to build gear myself is that even when you buy top components it still is way cheeper then buying the commercial available equivalent.
and the knowledge you gain when you build something yourself is unpayable. in the last 15 years i managed to "save" many sessions in the studio just by not being scared to open a box and to apply some solder or so, varying from amps, pedals, power suplies to synths, gtrs and fx, no to forget cables
