I think I need a new amp

[Nola25]

Hi

Was trying to diagnose and rectify a hum between my TT and amp this morning and touched the wrong wire on the cartridge resulting in the amp tripping.

Turned it back on and played a record and I've lost all treble through the speakers, headphones work fine as do the speakers through another amp so looks like I need a new amp.

With a budget of up to £500, what would people recommend?

Main features required would be a built in phono stage and an integrated CD player

Cheers

It sounds like you have blown your tweeters, rather than the amp.

If everything else is ok....

He said they work fine on another amp...

Ah, my mistake.

Seems odd though - only losing treble. Unless the description of the fault is not very good!

It is weird, but both speakers (woofer and tweeter) work on another amp, just not on the Nad.

Tried another set of small 2 ways on the Nad amp and the tweeter is dead on those too (small Mordaunt Short units)

Depending on the age/value of the NAD there are several places that could probably repair if easily enough?

I've had mine repaired before and it continues to provide sterling service.

Does the amp work OK with another input like CD?
If so, the problem is narrowed down to the phono stage. Pretty much, at least.
People pay good money for semi-broken amps on ebay, so paying to get it fixed may not be the best way forwards if you fancy a change.

If you can stretch that budget a tad you'd be into an Audiolab 6000. Full tilt modern amplifer.

Alternatively, and well within your budget, Marantz PM6007 is a serious contender. (About £450)

Thanks, will look at those 2 suggested

Tried with another input (have a separate phono stage) and it’s dead on all inputs

It’s an old amp (iirc I bought it in 2005/6) so probably not worth fixing.

If it's a half decent make, it will get you a few beers worth on ebay 'for parts.....'

Personally I have enough amps 'for parts..'
2005 might be a bit modern though!

You could look at used. £500 should get you a Meridian 551 Integrated. The later G51 will still be over that budget though.

The NAD will likely be worth fixing.

Find a local repair guy.

Old stuff refurbished likely hold its own against new stuff.

Did exactly this, found an old guy in the village, via my sons nursery owner, that potters with electronics and he’s fixed the amp (not 100% sure what was wrong but I’d blow something that sends the HF range from the amp to speakers)

£20 and a bottle of wine and my old Nad is up and running again!

However, day after the amp was fixed, my toddler shoved a toy pig into the tweeter foil and looks like I need new speakers now 😬

i've fixed a couple of my amps, but once things start dying of old age, the next part failing seems to come around annoyingly quickly.

Also the quality of replacement parts can be a problem, I've put in new volume pots only for them to go crackly in under a year.
I have Cambridge amp which must have worked for 15 years, a transistor died, then the replacement transistor died after about 18 months.

It's OK if you enjoy playing with this stuff, it might not look good to charge someone for a repair and the amp breaks again.

Since people seem to pay more than I do for broken amps to fix, flogging it and buying a nice new one with a warranty might not be the worst way forwards.

It seems an odd fault to kill the treble in both channels and have the bass still working.
I guess something like a dual op amp in the tone control section has been toasted?

[Nola25]

I’ll see how it goes, it was my clubhanded attempt at sorting something that killed it in the first place so it may have a few years left

I’m all likelihood, once I start looking at speakers, man maths will say I need a new amp anyway and the Nad can be relegated to the garage

Pushed the button and order a new set of speakers and a new amp today

Ended up going for the Marantz PM6007 amp and CD6007 CD player in silver with a pair of Q Acoustics Concept 40’s in white.

Nad amp and the now bastardised B&W’s (wired a pair of Monitor Audio Radius 45’s to the tweeter feed and stuck on top with blue tack) have been relegated to the garage .

I guess there’s bad crackling from that speaker now?

Glad you got the old NAD repaired, would have to spend a fair bit new to match it.
