Antique Sound Lab MG-SPM25 Output Transformers
 
Hello,

I think to build an Antique Sound Lab MG-SPM25 25W KT88 class A mono block amplifier with my own components (i have all components except output transformers). I have a doubt about output transformer primary value. Can somebody could help me ? I think of a standard 2,5K or 5K or 8K ? (ASL sells transformers but no corresponding)

The schematic is here http://ptsoundlab.jexiste.fr/depotimg/spm25.jpg


An other interesting amplifier is ASL AQ-1001 50W class A KT88 amplifier. If somebody know output transformer primary value, i will be please because I have some components too. http://ptsoundlab.jexiste.fr/depotimg/aq1001.jpg

Thanks experts ;)

Cordially

Pascal.
