Spare time + me + trademe = trouble.

While waiting impatiently for my cartridge and headshell to arrive: (http://www.audioenz.co.nz/forums/showthread.php/12929-Dipping-my-toes...into-vinyl), I was trawling through trademe and managed to pick up a vintage Kenwood KA-305 and a faulty Pioneer A-400x for $40 each.

The Kenwood sounds a lot better than I expected, and it might even replace the Cambridge which I have never become attached to. It probably doesn't have the same clarity as the Cambridge, but the music seems more involving and enjoyable (please excuse the very nontechnical descriptions). The only issue is that it seems to have more juice than the Cambridge, and there is a channel imbalance at low levels. Is this likely to be a reflection on the age/quality of the amp, or is it something that can be fixed? Both channels are the same volume when you go past 1 on the dial.

The Pioneer has a crackly and muffled left channel, so I'm keen to get it fixed. Anyone know of good repairers in Dunedin? Otherwise I might send it to Retrotronics in Auckland, but would like to avoid the $50-$60 in shipping if possible. Any other recommendations would be appreciated.

As my far too sensible girlfriend said, "is it still a bargain if you weren't going to buy it in the first place?" And she may have a point :) But the Kenwood seems like a very enjoyable amp for the price, and if I can get the Pioneer fixed for $100, then it might be a very cheap upgrade to the Cambridge. I was planning on spending $1000 on a new amp when back in gainful employment next year, but if the Pioneer sounds good, then that money can be allocated to buying vinyl :D

Have you tried cleaning the controls (deoxit or contact cleaner/lubricant) and if you have a meter and suitable information checking DC offset and bias? Pretty easy to do and there is lots of guidance available on the net if you need it.
These can help minor problems but there is potential to make things worse if not done properly (and also the hazard of working with electricity).

Thanks for the comments. I wish I knew how to do those things. I'd love to learn sometime, but would much prefer for someone to show me 1st hand than read off the internet (which completely goes against my nature, but I draw the line when dealing with electricity) :D
Might get in touch with Retrotronics about the Pioneer tomorrow, unless there are any recommendations for repairers in Dunedin?

Bob only does guitar amplifiers unfortunately.

Does anyone have experience with these guys?http://www.frontlineotago.co.nz

Not sure if I'm best to take it to any old appliance repairers, or send it north somewhere to an audio specialist?

Buy a can of de-oxit first, the move the switches and volume control a lot. Then take it to a tech- try to fix it yourself first, much cheaper!
