Acom 1011 Amplifier

[Denmark]

I'm getting one of those in December and i have been looking in the manuel for tunning it the propper way, and and i can see were the load and plate needs to be on each band so i wounder if any one know how it done the rigth way so i dont below anything up.
I know that the MAX power the amp can handle is 60watt
But what mode section is best for proper tunning : CW/USB/LSB/AM/FM

My radio setup is :

Radio :Yaesu FT450D

3 Element MONO Band ZX Beam

The amp will be used in 11meter band

Greetings Denmark

Captain Kilowatt has a good write up on this subject.

The owners/users manual for your amplifier if you get one will also have step by step instructions on how to tune the amplifier assuming it is a tbe amplifier with plate and load caps.

Looks like a decent amp 4cx250b ceramic for finals, looks like there is some type of tune indicator built in.

Looks like a nice amp, most manufactures reccomend tuning in the low voltage or CW position then once tuned switch to the SSB or high voltage and use it for phone on SSB.

Your amplifier will come with detailed instructions on how to tune it in the manual.

this amp had caught my interest also but i am undecided on the 1010 or 1011. I don't know is there any truth to the rumours of scarceness of the svetlana tube. in the 1010

Hey Waverider

Thanx for the helping hand i just looked in the manule and it says something about do the tunning in CW with low power and then when it tuned raise up the driver power on the radio and then your done looks easy enoff..

Yes that also slipped my mind on those tubes thats why i'm getting the 1011 model it also got 2 tubes instat of just 1

one tube should be better though. a local hamateur I know recently blew one tube in a dual tube sb200. i think its a similar problem to series lorry batteries, that is when one tube gets weak the other tube quickly kills it. whereas with a single tube amp it can be run until the valve gets completely worn out.
