Great Product! Time Owned: 3 to 6 months.
I have an AL80B and a AL82. I always wanted Ameritron's grid protection boards but then saw these. They are a combination of grid protection and a tuning aid. You do need to watch Toms videos and then you are ready to go. You can tune up quickly while protecting you from pulling too much grid current. I did have to make a slight adjustment, with Tom's help, to the trigger point resister on the AL82 board. It was very easy to do. Tom is very responsive when you have a question.

Excellent product Time Owned: 0 to 3 months.
Was a little skeptical about needing this in my AL-80B, as it's a pretty easy amp to tune already, but went ahead and installed it, out of curiosity more that anything. Was really easy to install, just a handful of wires to connect in and can just as easily be removed if needed. I watched Tom's video a couple of times to get the hang of how it worked and it's really just as easy as he shows it. Literally tune up, perfectly, in seconds, and not have to guess if your grid is peaking too high.

Fantastic! Time Owned: 0 to 3 months.
The TOF-1 (without grid shutoff/reset) was installed in the used AL-80B I got a few weeks back. Works GREAT!

Take the time to see W8JI's videos showing the TOF-1 in operation. They're worth the look.

I find that with my amp, the TOF-1 gets me to about 98 percent optimum loading, just by observing its light. I can literally nudge the load control just a bit more and get desired grid current.

One nice thing is its response if pretty quick, so you can see if your "peaks" are over driving the grid, preventing RF splatter and mushy audio (aka, those guys a full 6-7kc away bleeding into your rag chew).

I may be adding one to my AL-811 just because it works so well.

Nice tuning aid Time Owned: 3 to 6 months.
This really helps to tune on the fly and protect the amp.
