Would like to purchase from Harbach, but it seems no option to deliver outside US / Canada.

Scott, get better soon. 73, KB3NG

Our entire family had Covid when it first started in 2020. I healed up in about a week, which was good because I became an at home nurse for five weeks. 😮 Each person is different but you should be okay since you got the vaccines. Get well soon.

Awesome Video. Pray 🙏 You Get Well Soon. W9BBW WISCONSIN

Thanks for the video.

Looks good.

Nice job as always. I enjoy all your videos. W9BBW

Great video you are very knowledgeable Wonder why they never hard grounded the grids to begin with can you offer an explanation for educational purpose I would like to know. I am sure know more than most. Thanks and Happy late 4th

love your videos ....I have this amp and its been a good one so far but like you said , I'm thinking of getting mew caps due to age. thanks for the upload ......Marcus in west Texas

Did this amp get new tubes? thanks for showing this.

Another great video as always!

Pressure relief valve. Sometimes they work, sometimes the cap just explodes 😂 Have a great weekend.

Happy Independence Day to you and your family.

Have you ever had to replace the Band switch on the PCB? That switch is very delicate. Who knows where you even get one.

For the love of God man please do your best I consider the HENRY 8k my dream amplifier. 🙏 im kinda old-school

Nice work

Could you take the slightly broken air variable capacitors and rebuild them using parts from the really broken ones? Just asking because one day, they may not be available anymore. Thanks for the video.

Hey awesome stuff keep it up!

Great video. People shouldn't buy amps if they're not prepared to either fix it themselves or pay an expert like you to do it. An investment either way. Good luck. I hate dealing with idiots and selling gear too. Especially when they don't understand the time that's gone into something like this.

Another great video. BTW what is bias mod and purpose. 73 KK3R

I always enjoy your detailed work!!! Nice job.

Your work always looks top notch. 🏆

Great video. I know you don't work on Alpha amps. Anyone local (within tri-state area) that works on them? Dick Byrd hasn't replied to 2 emails ☹

Love the wood pointing stick. You can try wood chop sticks, they work well too. 😁. Lots of work there. Nice job.

Great job!

Recently picked up a 2006 al82, your videos have greatly helped my understanding, 73.

Awesome Job as always 73 Curt W9BBW

Hey there, I hope you're well! I recently acquired an AL-811H, but unfortunately the "Load" variable capacitor is not turning smoothly throughout. Seems to get very tight around 5 through 6. As such, I fear some of its plates may be contacting. I suspect this because the amp was shipped to me with tubes installed and unprotected, which resulted shattered glass inside the amp throughout. Initially, turning the "Load" knob did not actually turn the rotor, where the knob was just rotating on a stuck shaft, but with some finessing, I was able to get it to rotate the rotor. The plates on this variable cap are so close together its hard to tell if contact is being made, or if the shaft itself is just damaged in some way which is less concerning to me. I've noticed that MFJ sells a 282-2113, a 20-823pf replacement, however, given the fate of MFJ, I'd be surprised if this is something they would have in stock... none the less I have not contacted them yet. I have yet to drive the amp, as I fear a short on the "Load" however, for what it's worth, the Grid Current with no load is 1700 with some vintage RCA 811A's installed. Two questions for you: Is this something you would be able to address if i solicited a repair from you? Alternatively, would you happen to have any recommendations for a replacement? Returning this seems to be out of the question since it was a private sale of a "Works Good" amp. Thank you so much!

Looking great K0UO

Those right angle drives are such a space saver in the rf deck! Wish someone was still making those?!! Nice work!

73s buddy have a good night sleep well .

Rest and relax you doing good stand strong

i have a 811 keeps blowing the metre protection diode any thoughts, thanks.

Always good job

Hello Sir. Where are you located. I don't want to call when you would be in bed.

Nice work as always!

I notice the Harbach kits have 100k bleeder resistors instead of 50k, is this a better idea? Just refurbishing a Heathkit SB1000 in the UK. Look forward to you getting international shipping sorted.

Always clean rebuilds. 🏆

8021 is a beautiful amplifier. When you have the Rockwell Collins control head, and matching radio. They're pretty much is no bands you can't conquer the mission you can't generate. It'll even do slow speed data. And in the last Incarnation had a ivits system built in

Nice. Looking forward to see her power up. 😊

100mw of drive is wild.

Scott, believe it or not, this video helped me diagnose my SB-220. All of a sudden I had a short in the 120 VDC circuit. Initial symptom was SoftStart relay wouldn't disable. I checked ACV and DCV both were way too low. Check for shorts, soft start - nope, soft key - nope, capacitor - nope. Seemed to be coil for relay, then I disconnected the coil Still has short. figured I'd watch your video and do mod as part of the repair. Your comment on Grid to Heater short was the key. Thanks so much!!!

Thanks Brother. 73
