Perfect Thank You!

Does anyone know if this 36hpf needs to be modified to talk on 11 meters? One other thing I noticed is this model doesn't have FM like it's previous counterpart. My guess is to save production costs & who really uses FM?

I never said the sound quality was "poor" on the Motorola mrf455 transistors. I said the Mosfet amp sounded "Much better" Both amps were used with the same direct injected audio system so they were not being overdriven & had plenty of head room.

All Original dual stage one owner with original d&a Magnum tubes still works as good as it did from day one.

The Palomar ERF9530 is what the Rocketbox website says is used. IDK for sure but Whatever they are they work quite well & have very low amperage draw. The amp pictured above has been through Hell & back for the past year & still works as well as the first time I hooked it up. The Sound Quality...

Ok let's see here first things first I will need to find a DeLorean that still runs & can get going 88mph (142km/h) in a short distance.

Here is a pic of the Rocketbox HD250 that was assembled at Rocketbox.

It Looks Powerful

Rocketbox amps all have automatic Sideband but if you build a RB kit you will have to enable it. There is a YouTube video showing how that's done.

I Agree & it's just too bad you can't afford to try one out for yourself. They work as advertised & draw much less amperage than a bipolar pill box at 14 volts.

Ran the Rocketbox HD250 all summer long & put it through HELL averaging 30+ hours per month keyed and I will tell you this.➡ IF you operate this amp within its specified drive limits it's builder recommends they are very good "Sound Quality" amplifiers & the closest to the Tube Amp sound you...

Great Idea! So far my 50 year old speaker is still sounding good!

Or you could just get rid of your d201A parts radios & buy a Real Tram ;)

42 X 14 =588 so your watt meter may be a bit loose.

I thought all I had to do was wrap the fuse in aluminum foil & that would solve the problem.

Thanks, I'm sure all of this has happened & you are correct Mike is a great guy. I guess it's all water over the dam now.

Not bad for the extra 180 watts your getting!

Thanks for the interesting & Valuable information on this subject!
