I'd like to hear your thoughts on breaking in new amps.
1- What do you do, if anything, to break in your new amp?
2- In what way does the tone of your amp change during the break-in period? How does the sound change over the first year or two of playing?
Thanks.

I plug my I Pod into it and let it play for a few hours every day at different volumes.
Wife out= loud
Wife in= quieter.
Girlfriend in= off ^

i was thinking that it was the speakers and not so much the amp, when the cones become softer around the edges so its not so stiff.
i think the valves aswell are all clear until they get used then the mirror type effect appears on the top, i could be wrong but i remember reading somthing like that somewhere

Hey Mr TMF14.
I bought some tubes and the seller told me to put them in and run the amp for 24 hours. Is that "burning in?"
I play NPR/local classical station thru my amp for a couple of days to break in the speakers?
Am I nuts?
Thanks>

@ Jimbo G "i think the valves aswell are all clear until they get used then the mirror type effect appears on the top, i could be wrong but i remember reading somthing like that somewhere"
This is not the case, where you have silver inside the tube, on the glass envelope, this is called "getter flash" it is material that is used to suck up the last bits of gas in the tube. If the tube develops a leak, or there is air ingress via the pin holes, this silver often turns to white powder and is a sign that the tube is bad.

@6SN7-white noise is prefered for speaker break in,but I think NPR would do well.
"Burning in" really involves the caps and resistors,caps more so. The idea is too have them fully charged and hot,and maintain that state for a period of time. The timeframe? That differs by who you talk to,values and so forth. Most people would agree with 24-48 hours.
Also,"burn in" is usally done by the amp builder/tech to make sure nothing is faulty before the amp leaves the shop.

Do you think it is a good idea to take it easy on an amp at first?
Also, please tell me how the sound of your amp changes over the first couple of years.
