    Well, I rest my case with you guys. I guess you are that kind of people that have a closed mind and want to stay that way.

    I normally place my amp in the oven for 30 minutes before listening. :D

    Only to those with mis-information and mis-guided quotes...thanks for visiting...please come again....

    Thread went a little off topic"hot amps/warm sound" but I'm sure designers provide adequate cooling and do they also have thermal/overdrive protection built in?

    lol.This is not science it is a fact! Heat is the enemy of electronics unless it is a heater lol.

    Excess heat is a problem. Electronic components are engineered to work within a heat range. While it might appear hot to you, it is normal to the component. That is science, and a fact. :cool:

    ok, so "IF" Heat is so BENEFICIAL for audio, WHY do you need "proper" placement, ventilation, fans, vents?:rolleyes:

    Heat is absolutely needed if you're playing audio through vacuum tubes and will sound best once it reaches the proper operating temperatures which can be extremely hot for a lot of power tubes.

    lol. ok now apply more heat to those tubes and lets see if they will last 20 years.

    I didn't say in any of my posts to run any piece of electronics outside their normal operating parameters. OF COURSE if you run any piece of gear outside it's SOP it will fail and many times it can be because of heat.

    of course "PROPER CARE" given to a gear can negate or eliminate the risk of heat damage to electronics. but my point here is HEAT is not good for most of electronics.

    Before you said heat is the enemy of ALL electronics and now you say MOST. Which is it?

    I am not saying it can not be avoid...I am saying it should be avoid as much as it can be!!!!

    Why does all my class A gear and tubes sound better once they get cooking. I need about an hour for the amp and pre-amp to reach the best sound which coincides with when they are cooking? Apparently you know more than some of the finest amp designers in the history of audio.

    So we should all throw our tube amps and class A in the garbage because they get too hot and will prematurely fail? OK, in the garbage they go :rolleyes:

    l of course tubes are less reliable and also they need more maintenance. but again, What do I know.

    Many NOS tubes are much more reliable and rugged and can handle adverse conditions much better than many transistors or IC's. Of course one of the weak points for tubes are if you drop them on a hard surface. So you don't know.

    Anyway, I'm done with your circular logic and you keep contradicting your original stance.

    My amp has proper ventilation and you can't touch the massive heat sinks for more than 7-10 seconds before you feel serious pain. The amp was designed this way, the parts used are operating well within SOP, these amps never fail, they last as long or longer than cooler running amps. So your blanket statement is just wrong.

    Power output tubes are spec'd for operating temperatures at the glass envelope of 200 degrees Celsius (392 degrees F).

    Most high voltage power transformers are spec'd for operating temperatures of 190 degrees Farenheit (88 degrees C).

    Source for the above data: RCA receiving tube manuals (available at www.tubebooks.org)
    EICO amplifier construction/operating manuals (available from the EICO Yahoo group).

    Capacitors are spec'd for (maximum at full rating) operating temperatures of 85 or 105 degrees C.

    Hot is (often) OK, and often an intentional feature of a design.

    I was wondering....
    If I was to give this pre-bake method a try.....what would be a good temperature setting, say maybe 550 F, would be a good starting point??

    No way! 550 will burn the wire insulation. Go lower. I let mine cook in the hot afternoon sun for 30mins.

    I think it's really HOT in this thread.

    Try Air Bending, anyone? :D
    Trying out Different Audio Cables is a Religious Affair. You don't discuss it with anyone. :redface::biggrin:

    Complete bs here...:rolleyes:


    If you want real sonic improvement, set the oven to BROIL for thirty minutes and then CRYOGENICALLY freeze them in liquid nitrogen emediately after they come out of the oven.

    Even a Fisher Price phonograph will sound like a 12k table after going through this.:D

    The warmer my house the better the system sounds. Of course the house heats up after those tubes have been on for awhile so maybe its warmup time issue.

    Avantgarde horns, 300b tubes, thats the kinda crap I want... :D

    I think we can all agree that leaving your amplifier off instead of using it at room temperatures will increase the lifespan lol.
