Hi, first post, so please excuse any toe treading.
I recently rescued from my late father in-laws basement a Beomaster 1700 tuner/amp which had been down in the damp for over15 years.
It looks like he had a nasty accident/short and literally burnt several resistors on the left channel side of the output amp. I'm not an electronics expert so I took the belt and braces approach and replaced all the burnt components, all the transistors and all the capacitors (except the pair of big 5000uF ones) on that side of the amp.
By some miracle the thing works, (and after a clean and a respray of the base, looks fab) but the sound it produces is sort of "empty". It's playing though a pair of good condition RL60's, QED speaker cable and the source is a new, resonable quality CD player (which works very well on my Jap stuff). It's not lacking volume, just sounds like it's playing through 6" of foam. Both channels sound this way, not just the one I've rebuilt.
So, if anybody has some idea/suggestions of what I should do/how to sort this fine piece of kit, please, I'd be happy to receive them.
I'm considering changing the 50000uF caps and replacing the components of the tone control board as I'm sure the years of damp haven't helped. Also, do I need to source any particular type, manufacturer or quality components??
Cheers, Mark.
