Never said it's on its last legs. Anything that has moving parts will eventaully wear out, such as cars, vans, CDPs, turntables...
The point I made is that if you buy an amp that was made in the early-mid 90s with faults, chances are, sooner or later, it will show other problems. I'm just trying to be realistic, and unless the OP has the amp modified, it will keep on costing money.
Not helpful for the novice who has just purchased a good entry level Hi-Fi amp which only has a noisy pot though.
Amplifiers can usually be repaired. Parts, even if discontinued, can be substituted.
Can be a little more tricky with cd players
Pretty ... and pretty proud of it
It's not a point of View nor is it misguided. All mechanical items wear out. That is a fact. Otherwise there would be no scrapyards or recycling centres.

Your just being argumentative. Won't reply anymore to your posts.
My view is that old amplifier that shows signs of wear is not viable unless you are prepared to service yourself as a hobby exersise. If not you will need to pay someone to fix it for you. Unless your are attached to the specific sound a new amplifier is the way to go.
Pots showing signs of wear best will be to replace them really.
Switches and connectors can start playing up too.
Not to mention the major component that affect sound are the capacitors when they get old. So replacing all of them will be a good exersise.
Beefing up the power supply could also show improvements to sound.
Thanks for the decent advice; I get sick and tired on formus of people beating down other's gear; I'm sure it's a snob thing; some people don't like a certain brand and feel they have to have their say!!! I only asked if I could somehow fix the pot crackle!!! I earn minimum wage at the mo, and don't have any savings so a 20 year old Whathifi award winner is good enough for me!!
I TOTALLY disagree that if any piece of equiment has a minor fault, it means it will lead to more faults....nonsense!!!! I'm sure he's just gutted my amp was cheap and better than his
In terms of speakers, the A400 was noted for its synergy with Mission. The A400/ 780 combo is brilliant, and the 75 series (751, 752, 753 and their 'Freedom' siblings) make a particularly impressive combination.
Definitely worth getting the '400 looked at- it's a cracking amp. I have a broken one that's been awaiting TLC for years... I've got weird, squelchy noises coming from mine (through the speakers) that get louder as the amp warms up. I've decided this isn't good and haven't powered it up since.
When my midlife crisis arrives, I'm going to strip it and do a complete rebuild. That's the plan anyway...

the A400 is for my kitchen; it's quite a big space probably 12ft x 30ft and at the moment I'm running a set of Kef Crestas until I can upgrade; My dad has always had Mission speakers and across the Net the 75x series are mentioned often.......What I am really after is the lows and highs from the speakers; I listen to a lot of electronic and dance music with barely and vocals so bottom end and tops are essential
The Pioneer A400 is an excellent amp with a lot of audio pedigree and its very very reliable.

For your musical preferences maybe pair it with 12" Cerwin-Vegas because they have higher sensitivity (93db+) and will play considirably loud with the A400's potent 70WPC RMS. I think the Pioneer solved your amp HiFi dilemas for a while. Now focus on getting good speakers for electronic music. The speakers are biggest factor on your HiFi sound performance. The A400 will drive any speakers up to 500 GBP with gusto.
To fix the crackle in the volume pot and the other 2 selector knobs, spray dry (not greasy) electronics cleaning spray inside the volume potentiometer and selector switches (on the main PCB board). As eggontoast said previously.... its maintanance, not repair. Take the lid off, power cord out off main socket and dont lean on any electronic parts with bare hands. Just spray with the can straw nosle in the potentiometer and 2 selector switches and work them a bit.
Congrats on an excellent purchase!
Thanks for your advice it really is helpful, and I am totally pleased with the amp. Do you know the Cerwin's model?
I remember reading the WHF review of the A400 like it was only yesterday. At the time I was kind of in the market for a new amp, but I was young and I couldn't bring myself to buy an amp which didn't have a loudness button and tone controls. I held off for a year or two then while WHF were raving about the new Kenwood 3020SE, I bought a Kenwood 5020 instead, which I kidded myself was basically the same amp with the all-important tone controls and loudness button. It wasn't, of course.
