4/21/00 - Retail Production ceased on Monster Amp.
I have come to a difficult decision and stopped making Monster Amps for sale. It takes so long to build each order that it takes up all my free time and has become a "job" instead of a hobby. Until I find a manufacturer who wants to take over production I've quit making them. I plan on offering plans and kits however, so drop me a line.  Due to Spam activity, you'll have to email me by decoding my email address.  My email starts with "bpeloquin" and the domain name is "hansondata.com", so if you put the two together you'll get (name)@(company).com but I can't include a link to it or spammer's robots will pick it up.

The Monster Amp is a small amplifier for your Walkman or other personal entertainment product. It is designed to boost the inadequate volume of your portable stereo for use in high-noise environments such as motorcycling. I designed the Monster Amp to be used with Collett's Bass-Monster helmet speakers. The Monster Amp puts out almost 1 Watt per channel and makes hearing your Walkman over the noise of the wind, engine, etc. possible even when wearing earplugs (I strongly recommend using earplugs when riding unfaired motorcycles or on any motorcycle when traveling at highway speeds for over 1/2 hour).

About the Monster Amp design

The Monster Amp can be constructed in several configurations. I've made 3 different kinds: Battery-powered (totally portable), 2 channel and three-channel (12-volt) models. Specifications

Portable  The basic model runs on a 9-volt alkaline battery and fits in your pocket. The unit is small, about the size of a TV remote control, and has an on/off switch with a 3 foot stereo pigtail lead and an 1/8 inch stereo jack on the top. The rear panel is removable for replacing the battery, which lasts up to 10 hours of continuous use. The volume is fixed at about 20 dB gain so you use the volume control on your Walkman to regulate the sound.

 

 2-Channel  This model is externally powered by any of several power options. The unit is designed to fit in your tank bag or Velcro to a convenient spot on your vehicle. It has a volume control and on/off switch on the front with a power cable and 39 inch stereo pigtail lead allowing you to place your Walkman away from the amplifier for easier operation. A 2'nd input jack allows you to hear your radar detector, CB etc. The 2'nd audio source is mixed with Walkman input and is controlled by the same volume control.

Power options:

 6-AA cell battery holder (runs for over 40 hours on a set of alkaline batteries)  
 9.6 Volt rechargeable battery pack & 4-hour charger (runs for over 40 hours on a charge)  
 External power converter (runs from 12 volt vehicle battery), includes 4 foot fused cable with SAE polarized connectors and standard power connector to mate with MA-2

 2'nd monaural input jack, 3/32" (2.5mm)
or RCA phono jack
 

 

 3-channel 12-volt unit  This model has the 12-volt power supply built-in. It uses the same KA2209 stereo amplifier but is in a slightly larger case. I installed 2 monaural inputs using RCA phono jacks. The headphone connector was moved to the front panel for easier access.

Picture of MA-3 soon to come
