Hey all;
I've been reading the forum for a couple of months now and there's certainly a lot of information. In fact I think I've read too much and now I don't know how to start.
I'd acquired an old Realistic receiver and a very old Sansui receiver, both of them are broke; no sound from the Realistic plus the radio doesn't work, and the chips in the sansui are burnt out, (receiver lights up though and tunes, just can't get a signal out, shame cause it's really good looking).
I was thinking about making an LM3875 chip with point-to-point wiring and a separate power supply. Theoretically i was just going to buy the LM3875 chips. and trying and make the rest from scavenged parts. Then I started reading about hum problems when using a point to point and it seems that using a PCB is the easiest way to get good results. I basically want to make something just for the enjoyment of making it and that I can cut my teeth on, I'd like to progress onto a valve pre-amp one day. I'm also intrigued to know if a diy amp can impress me with the sound
So my options are:
1) Stick to my original plan and make a point to point amp with shiny new chips and use the other amps as doners.
2) Buy a PCB and kit and make a good quality amp with a separate scavenged power supply. Why
3) Forget the scavenging and buy all new components.
I currently have a very old Realistic SA-1500 which looks beautiful and sounds very nice, (it was being throw away out in a clear out and I picked it up, the fuse and blown and the power light doesn't work. ) with a pair of old Paradigm SE5 Mk3's. My source is a slimserver music streamer. I don't know much about hi-fi but it all sounds rather good. So I want to try and make an amp to drive the Paradigm's.
Any advice on the best approach to take and any advice on scavenging parts from old equipment. Is it worth using old caps and resistors ?
king regards
