Found the hum on the AEG Solidtube tonight - after swapping 3 valves to
no effect, I thought it was a poor earth connection on the casing at one
point as it could be temporarily affected by gripping it here and there.
Then reading the service .pdf that someone kindly put me on to (Ian?
Iain? - I'm on a different machine, so I can't see who it was) I checked
and found it was the bass attenuation switch:


Typing ******** as usual - its a -20 dB 'pad' switch!


The sun always shine on the righteous, they say - let's just hope it
don't *hum*...!!!


OK, not so righteous it seems - the hum has become erratic and irrational
and it hums with the switch the other way now, so I guess it's gonna have
to go off for a pro repair.

(Too fiddly and will probably need parts....)


Before you send it off. A colleague tells me that this mic
has a spring through which the case is grounded.
Check that it is making good contact.


Done that, Iain and also trapped a bit of aluminium foil between the body
halves to ensure a bond, but it really is the switch - which means it is
likely be a coil on the board. Way too fiddly to be soldered with a heated
shovel and will want dinky little parts near impossible to get outside the
pro repair circuit, I suspect.

There's no rush to fix it (check your emails) and I can drop it into (or
post it to) a place in Letchworth, just down the road. It's probably/almost
certainly going to cost a wunnah or so to fix, which is what I budgeted for
when I bid on it knowing *full well* that it was almost certainly going to
have a real reason for someone getting rid!

OK. Just a thought.

If you mean Sound Technology, they are very good

It will still be a reasonably-priced purchase even after repair.

I thought that Harman were word-wide agents for AKG, so
try also: This may be old info.

And much appreciated! :-)

Yes, that's them!

Exactly. Apart from a one-off 'rogue' price of 499 GBP from these people:

http://www.guitarampkeyboard.com/en/akg-solid-tube/1512


These things seem to cost over 700 quid, which means I can afford to have it
repaired and it will still be a bit of a bargain for what it will have cost
me. The sound quality is there - much better than the Chinese valve mic I
had here (for even more money) and which was also noisy!!

Thank you for that - I did find them and looked at the website, but I
thought it looked a bit too slick and 'big time' for a little repair to a
****ty old eBay mic! Besides, I know where Sound Technology is and they
can't be too big - plus it's virtually on my doorstep! :-)

What a silly goose I am - I meant to ask if anyone could say what the
mics
were?

They look like modern SE 2000s - or the other way round:

Original Neumann U47 or Telefunken 201M


Iain

IIRC, Abbey Road studios had mics that were originally U47 and the converted
to U48s so its difficult to see from this distance - but definitely
Neumanns.

Please don't post links to *black and white* footage that I *actually*
remember.


This could be a "Where were you then?" I am sure most of us here
can remember. It was 1961. I thought HS was wonderful............

until I found Francoise Hardy. Love at first sight:-)


Yes, the French tarts of that era certainly had something

I never thought of her as a "French tart", - more of an "ange"
She drove a Maserati, - "une fille comme tant d'autres" :-)))

...and of course you had every chance of 'meeting' her...if your name
happened to be Bob Dylan or Mick Jagger.


Or David Bowie or Brian Ferry, or, or.....
One consolation was a newspaper gossip column revelation
where someone like Serge Gainsbourg told that bedding her
was like bedding a sack of bones:-)
