Marantz 1070 amp

Dear Network,

My faithful Marantz 1070 is starting to bear the weight of its age, but I just cannot let go of it... I recently relocated from Singapore to Stockholm. The 5.5 years spent in tropical climates associated with the shipping from Asia are causing my potentiometers to crack, and namely the channel selector. Would any of you fine people know of:
- someone in Stockholm who could potentially fix, rejuvenate my beloved amp?
- available spare parts I could purchase if it turns out I need to change components?
I "inherited" the amp from my dad, along with 2 Marantz speakers. I coupled all this with a Bose sound system and boy... It has been a wonderful journey listening to music with this combo!

Any advice, indication would be most welcome folks, thanks in advance.

re: 1070

The manual says to use r724 in the manual for one of the off sets but it actually means j724

re: 1070

Got a 1070 fully recapped and it completely blew me away. It is sweet, warm and full bodied sound which I can listen all day. This is the only Marantz equipment I liked after trying out all their post 80s cdp and amps.

Thanks for the manual. It is too nostalgic to read and listen something older than me.

re: 1070

Many thanks
