Sure would appreciate some help here... As I've posted somewhat recently, I got myself an Aguilar DB750 not too long ago (approx. 3 weeks ago). I probably should seek professional help, as I cannot explain why I'm having such a love affair with an inanimate object. This amp is so simple, yet she will do anything I ask of her... I told you I'm sick... Here's my situation: I have my DB750 rack-mounted in a 4-space SKB, along with a Korg DTR1000 tuner. I'm sure all y'all know that there ain't no more space left over. To date, I've not gigged with the Aggie... just practice sessions on Sunday afternoons, and Monday evenings. What I'm noticing is... 'DA HEAT!!! Since I've used the Aggie only for practice thus far, I've been working her kinda hard: I've been pairing-up my Bergie NV215 and my Eden D410XLT... both 4-Ohm cabinets. I'll leave it to your imagination as to the sound capabilities, but I do notice a lot of heat eminating out of the back of the rack. I've become a little paranoid, so I started blowing a fan at the back of the rack, but I also understand that the twin cooling fans are designed to draw the heat out of the amplifier. Here comes my questions: 1.) Do any of you DB750 owners have your baby stuffed in a 4-space rack as I do, and if so, any heat issues? If you have had heat issues, what did you do about it?? 2.) Since the twin cooling fans are designed to draw the heat out of the amp, am I contradicting the cooling purpose by blowing air at the back of the rack??? Bottom line thus far, ladies and gentlemen, is that my beloved Aggie hasn't fried any eggs, boiled any water, or simply shut down... she's been giving me all that I've demanded... so far. I would simply like to know if I'm just being overly concerned, or if any of y'all think I should do something different in order to preseve my Aggie's life... Thank you for your time, and I shall look forward to any, and all suggestions!
