Hey guys, scored a NewOldAmp today... A RSA Truvoice 15.. Believe its from '55.. Actually came with all of its original documentation! HArd to believe it all survived this long. Unfortunately there is no internal mains transformer so im not plugging it in until i get it sorted out via a tech but has anyone here any experience with these?! A long shot but you guys porobably know someone! PS ive been onto the vintagehofner website and my amp is actually the following amp (#629) to the one they have listed there (which resides in Finland!) .... Pics later when i upload them!
