Default Boomer Deluxe 500 Base amp


Hello i was wondering if anyone has ever wired a on off switch or variable speed switch for the fan on the rear of amp? My microphone picks up the noise where i like to run my turner +3B desk mic modulation. The amp is a straight 4 pills with 1446 trans. So how could i add this switch, what type of switch could i use? This amp also has the two lugs on front for mobile power supply. Any help would be appreciated.

You will need a variable it would go inline with the wires that run to the fan it would be spliced in. It would work kind of like a dimmer switch on a house light that is how the speed control could be set

I had the same problem here with my power mic picking up the noise from the fan...
I put my amp down near the floor and off to the right side away from my mic...it works good now......just a thought..

Hence the slang term "Footwarmer"

As a previous user of power microphones, including the Turner +3B and D-104, I say that the gain is too high. Your microphone should not be able to pick up the fan noise. I know a lot of guys crank the mic gains up and then lean back in their chairs about two feet from the mic and that's not the way to do it. Your audio would be much better with lower gain and speaking close to the mic. Just offering some advise learned from being in this crazy hobby for 33+ years. Use it if you want and ignore it if you wish.

Alot of people think you have to turn up that gain on that power mic so you can boom the airwaves Thats not the case all you need to do with a radio thats been peak and tuned is set the radios mic gain at 12:00 position and your mic gain by using a simple test using AM or SSB key the mic and watch your radios meter or an outboard power meter you shouldnt see any audio movement this is where SSB is the easiest mode because there is no carrier but even AM mode will show if theres audio there moving the needle above and beyond its carrier point.

Seeing movement on a deadkey is no good this means that you have your gain set to high and you need to back it down. some people do not have alot of background noise but when talking almost have that echo in the room that also comes from the gain set to high. You have to find that happy medium for each application or setup rather it being a mobile or base eitherway steps have to be taken to set it propery or your going to bring all kinds of noise with your voice on keyup.

As stated if you are one of these people that to like to (kick back) in the easy chaiir and talk into the mic then I suggest you get a handheld because if you dont plan on yelling to be heard in the microphone then you and others on the frequency are kjust going to have to deal with the background noise
