Burn-in period for a VTB1?

[billisa]

I have a pair of VTB1's, which so far I'm loving. Because I'm using them for commercial voiceovers they aren't on all that long. In another post I heard someone mention "burning-in" their preamp. Would it be a good thing, or necessary to leave mine on for, say, a week to do a "burn-in"? Is that too long? Not enough? Not advisable?

if you allready like how they sound, why screw with it?

You don't have to burn-in your VTB-1's... there ready to go right out of the box.

You can leave them on always if you want. Give it about 1/2 hr to heat up and stablize if you dont leave it on all the time.

The VTB-1 is a transistor preamp... so you don't have to let it warm up and stablize... and the 12AX7 tube section is ready to rock about 60 seconds or so after turning the preamp on..

Oh... Ill let Alan know to revise the booklet to remove his recommendations for optimum performance.

For arguments sake, you don't have to do anything.

It takes usually about 2 minute just for atypical 48v phantom to optimize? It also take more than 60 seconds for the air surrounding the tube to stablize. If you plot the curves of the tube it will more than likely cycle as the tube heat effects other components. Transitors also have optimum temperature ranges, these are usually given along with MTBF in the harshest operating environment. While you could probably say...its useable in 60 seconds...it certainly isn't stable or optimized. All electronic gear is this way. While many folks may not notice changes over time because of heat...there are many that do.

My studio stays on 24/7 so I've never run into that problem... but thanks for the tip and I'll reread the VTB-1 manual.
