hi,
Newbie in DIY, i'd like to try some modifications on a Rotel RC 971 pre amp. First, change the AD 707 opa for a 825 on, the JRC's (they seems poor quality), the pot for an Alps one and the transformer for a toroid unit.
Does anyone made those modifications on this model ? (yeah i know, i know.... it's not a top product but ......) I also need the values of the tranformer, if anyone has the manuel service ? Well any advise will be welcome.
