I have just joined this forum being a new owner of an old amp as above. The sound is exactly what I am looking for, and every time I play it I undergo a great melting moment and have to do a long breath out after playing to "recover". Joy.
This amp has a low/high control. Will it shorten the life of the tubes if used in the low setting? I have read somewhere that it could be an issue, but cannot imagine why it was incorporated if so.
It has also been modified in the past. The phase inverter (?) .valve has been removed, and the diagram with the tube layout has had that valve scribbled out. Whilst this does not concern me as the tone is so good, I am interested in what has likely been done.
I have found that although the trem sounds great, it does take some of the full tone away. Is this to be expected\? I find that an increase in volume can make up for this.
The speakers have been replaced at some time by two Celestion 25W G12M's. Although slightly under powered for the combo they do sound good. I will be careful with volume, but seem to be coping very well at volumes I consider loud, and that is coming from a history of AC30 use.
Lastly the previous owner had a waterproof ON/OFF HI/LOW switch put in as there was some issue about moisture ingress?
I have tried to research these topics but have not found any satisfactory answers, so apologies if they have been covered before.
This is one great amp.
Thank you for any enlightenment.
