Mrf300 by 4, water cooled hf 6mtr amplifier

My Hone Brew amp using 4 x mrf300, as per my other videos of a Melbourne made Amp board sold on eBay by a Vk3, basically those boards,
Had 4 x mrf300 , barely made 600 watts, so I stripped that board of its parts and brought some boards out of the EU, the results are so much better
One board two devices easily makes
620 watts as per my last video, and here in this amp
Two boards 4 devices easily makes
1200 watts, I say easily as I still can crank up the input to 70 watts
Leaving 7 watts after the attenuator .
Any one who would like to talk to me regarding one of these amps,
Please email me at [e-mail]
Just remember this is just a hobby
For me, not a profit making venture.
If I tried to bill the hours for my time, a spe2kfa
Would be a cheaper deal to buy.
Still it keep the grey matter busy.
