blown Rode NT1 phantom power mic

not necessarily an evil sign. often the gunk is intentionally placed there.

most mics of this type are built to take that.

the NT1 sells for about $200 at present. yes it would be a thrill to fix it yourself, however I'd suggest something less costly and easier to practice on as you break in to electronic repair.

Rode mics in my experience are instruments to be proud of. My NT-5 pair provides exceptional service.

a mic like this deserves the care and attention an experienced service tech can bring.

perhaps you could get one of the cheap Chinese made condensers on e-bay to practice on.

Don't know what valve is in your mic but you might be able to look up a schematic for that valve here:

A *valve* phantom power mic? Don't think it's possible. Not enough current available from a phantom supply.

However, the Rode NT1 is an FET design.

Didn't know. Got wrapped up into reading about people converting some other mics to valves I guess.

As far as the phantom power goes, you're probably right as they generally provide less than 20 Ma.

That is not good.

Some ideas -- see the capacitor and resistor?

Well, I've been using phantom mics for well over 30 years, and have

Yeah I never turned off power on my mics either and havn't had any problems.

Perhaps some don't realise the idea behind phantom power. Before it we had things like T power which didn't like a dynamic mic plugged across it - and the mic might not like it either. So the whole idea of phantom was to have a supply 'transparent' to both phantom mics and dynamic, to make rigging large gigs easier. And having to turn off an individual circuit - even if you could - to replace a faulty mic would be untenable.
