I have a celestion greenback speaker thats blown...
Is it worth trying to fix it?
Or should i just get a new speaker?

Now if I was the rock star I always hoped I would be, only to be able to buy my dream analog consol that sits close to my fine listening / study room... I might buy these gems for around $120,000.

I'm sorry if this has been answered before but I could not find it searching the site or with google.

I play a regular outdoor gig throughout the Summer here in the UK which has my trio set up under a band stand with open sides but overhead cover. I have recently purchased a tube amp and it got me thinking if outside playing can damage a tube amp. The gigs are May - September and many of them are in the evening finishing at 10pm.

Hi all,
my dbx 386 has started giving me some horrendous noises on one channel. I've tried switching the tubes between channel 1 and 2, and the same channel still has the problem, so obviously my tubes are fine. Does anyone know where I might get a hold of some schematics so I can track down the problem?

Alternatively, can anyone suggest where to start looking?

Hi. I hope that I am posting this in the correct place. I have a Revox A77 2-track R2R and the other day, a small puff of whitish smoke came from the left lower part of the machine. It continued to play in the short time before I could turn it off and unplug it.

Any idea what it may be and where to look? Thanks.

Hey,

I am looking for a schematic for an old Neve 31105 Mic Pre. The reason is that the studio I work at has a few that are in need of repair. Our tech said he could do it if he can get a schematic. I am aware that many schematics are under copyright and so any other useful information on these would help as well. Thanks!

What are some of your favourite circuit for this voltage?
Has anyone used the Linear Regs like the Supertex inc. LR8?

Just to get the ball re-rolling. .

So I am playing with a simple op-amp circuit to test a new PCB. I just need a quick adjustable gain so I threw a pot in the feedback path in a non-inverting configuation...

For sometime now I have looking all over the net for a thread about the various ways to spice up your mic pre or compressor or well anything…. by adding a little subtle distortion.

Boxes like SSL alpha and UA twin infinity pre add a 2nd or 3rD harmonic generator that allows the user to dial in a bit of distortion.
