Good morning from the Netherlands, my Acom 1500 is now 8 years old with the original tube, so i thought i would get a spare just in case ,i get from 30 watts in around 450 out, so i have some time to go, but i found the cheapest place to buy a new tube is from Acom, 300 euros cheaper than any shop in the Netherlands, and buying direct from Acom the quality is assured,,,,,,hope this has been usefull,73 from Rottedam....
Hi, good video well explained, i now know what to do ,i have a spare second hand tested tube for emergency do you think there could be installing issues,thanks and 73 from Rotterdam
Good to hear from you and thank you for commenting. My old tube had a fault but it worked great up until then, so I won’t replace this one until I see another fault. Probably many years from now 🤞It was pretty easy to change IMO. That said, it can kill you if the right precautions are not taken. Best 73 and good DX! de KØPIR
Did you notice a power output improvement with the new tube? In the previous video you were getting 850w with 60w drive. How is it with the new tube at 60w drive? I'm thinking of putting a new tube in mine as it only makes 650w with 60w drive. Thanks VE3WF
It's nice to hear from you David. Yes more output now with less drive. Fantastic amp and after seeing the new solid state amps at Hamvention I think I'll stick with this one for a long time to come. Vry73!
Hi Jay, it’s nice to hear from you and thank you for commenting. I do have it and still use it. The power output is fine and I wouldn’t trade this amplifier for another. I hope this helps.
It can be downloaded on the net as a PDF but find the manual for the model amp you want. It will show all the different operating voltages on the primary side and the jumpers to move from 100-280v roughly. You might have to decrease drive to prevent the amp from pulling too much current out of the wall or getting voltage sag on the filament when running it on 120v.

@@HamRadioAdventures thanks for the advice, 73..👍
so sad that ther is no more Henry radio, Alpha and so on....
Agreed. So few choices these days and the expense leaves many out. Merry Christmas!
Could i ask how you actually blew the tube?
Just got old. Probably the original. One day the error popped up after I powered it on. 73!
@@HamRadioAdventures what was the code? I think mine is starting to get weak and now its going to be difficult finding a tube.
@@1112223333111 it was a long Protection Error that started with PR06... see www.k0pir.us/acom-1000-tube-replacement/ Thanks and GL my friend!
@@HamRadioAdventures did you have to getter the tube?
@@1112223333111 Yes, got it off of eBay. Works FB. 73!

Do you still run this amp ? I was looking at these or om2000+ but the om has issues it seems. How’s the power now

anyone know how to calibrate the TRI system after replacing the tube?
Try their support e-mail address too. i don't want to post it here. My e-mail is good on QRZ.com
@@HamRadioAdventures I emailed 2 years ago. they dont reply
@@1112223333111 my email is good on qrz.com. Send me an email and I’ll forward the email I have for them to you.
do you run this at 120 or 240? I'm thinking of getting one, but only have 120

Hey guys. Maybe a dumb question. So it’s a 220 plug. Then ?? That has to be plug in the wall.

How long has this amplifier been in service? K7NFO
Hi Mike, It's nice to hear from you and thanks for commenting here. I've had it about 3 years but it was in service long before that. Vry73!
Silly amps?
Cute
