Review Summary For : EB104 Group EB500
Reviews: 1MSRP: $920.00
Description:
The EB104 group offers this 500 watt MOSFET SS amplifier with a TFT touchscreen controller. It can be ordered for 5, 10 or 20 watts input. It is well protected against high SWR, too much drive and many of the other errors that do bad things to Solid State amplifiers. It requires a 53 volt DC supply that will provide approximately 20 amperes. It's quite small 6H x 9D x 11 1/2 W and weighs a huge 12 pounds!
Product is in production

Very Nice Amplifier and Excellent Support! Time Owned: 3 to 6 months.
It was a pleasure dealing with Yana and Victor. They were very nice and were easy to deal with. As far as support, they have been absolutely top notch! I had a problem with power measurement and their replies were quick and they went the extra mile to be sure.

Also interesting was that Victor recorded the final testing and posted it to YouTube. I was able to see it go thru all of the final tests before it was shipped. By way of explaining the issue I had, Victor pulled an amp off the shelf and recorded another YouTube video explaining my results.

The design uses a rugged pair of SD2933 MOSFETS. The construction of the amplifier is excellent. It's quiet. There is little or no fan noise. It can sit next to the microphone and you'd never know it was on.

The protection circuits stop me from doing stupid things every time! They check for high SWR, too much drive and excessive power or current.

Overall, the amplifier is a bargain and EB104 support could not be better!
