It made sense back when it was built and the tubes were $2 each. It's more of a curiosity than anything else now. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent with

*** When I built my homebrew amp back around 1971, I bought the 6LQ6's from Radio Shack. They had a lifetime warranty on tubes. I carefully put the receipt in an envelope, and taped it to the bottom

The somewhat haphazard lettering on the front panel does suggest homebrew. That looks to be a about a 300 Watt amp. Maybe 400-ish PEP if you push the tubes to the ragged edge and add forced air

Looking at the picture magnified, it does look HB, although a well done HB. Thanks for the replies, 73, Dick, W1KSZ ________________________________ Sent: Wednesday, April 17, 2024 9:31 AM To:

This is definitely a well-executed homebrew that someone made to match his station, though the front panel may be the only thing that had to be modified. I say this having seen examples of “Drake”

A real Drake LA-4 is an Audio Line Amplifier. Not what is shown on the auction site, which appears to be homebrew. Interesting effort, though. Jerry, N4JL Sent: Wednesday, April 17, 2024 11:49 AM To:

My GUESS would be, that this is an interesting home brew fabrication, but who knows? There were a lot of CB amps built with 2/4/6 sweep tubes. These days, it would cost a fair amount just for 6x

Interesting - 6 sweep tubes. You'd need to gin up a power supply for it; I'd guess 800V at a half amp or so + filaments. The connector looks a little oddball; like an octal plug, only 11 pins. I think

Anyone ever heard of this amp ? A Google search comes up empty. It's listed on that Auction Site. 73, Dick, W1KSZ

Paul, Thanks for the feedback – and to Dale, W4OP for posting his Si5351A spectrum result. I’ll have another look at the PLL VFO’s output. My memory may be mixed up with the result of a

Paul, Thank you.? Very interesting.? I don't plan to ever get a 2NT but others will probably find that info really interesting. Someone could go to ebay and by an Si5351 board for $5 and an Arduino

Thanks!? This is very helpful!!? Really appreciate your patience with me and my poor technical skills. 73, Bill NZ0T

Paul, I'm sure I responded to your post, but don't see it here, so am responding again. The Si5351A output is adequate to drive the 2-NT to full output on all bands. When operating straight through,

Gary, I thought I had replied to W9AC's message. Not sure where it went, so here it is again. The Si5351A output is adequate to drive the 2-NT to full output on all bands. As shown in the pdf you

The PIN attenuator has no connection to the meter circuit. The forward wattmeter voltage is also fed to a Norton op-amp on the ALC board though diode CR1602 in parallel with a .01 capacitor. This is

The meter works fine on RX and the S- meter adjustment worked perfectly. The problem is in TX where the meter reflects down below zero. In the circuit description in the SM on page 1-2 that there is a

I don't think your problem is with the ALC board. You need to find out where the voltage that is causing the meter to deflect downward is coming from. The meter is driven by the wattmeter sensor in
