Dear All, I completed the AMP10 and I am very surprised about its power and quality of the sound, amazing stereo effects, dynamics! My question is about the temperature in LM317 regulator, the metal heat is at 100°C fixed the TA2022 is about 60°C my power trasformer is a 24+24 VAC 160VA. I am quite bit worried about the 100°c on the LM317. I didnt find a 22+22VC trasfo. I read the LM317 technical specifications and they tell it can run with voltage input of 40VDc. I am using the AMP since 2 weeks and for many hours continuosly (need to discover all my music tracks again with this super AMP :-) ). Do you think I am going into trouble to have this high temperature on LM317? I think for the TA2022 60°c is not so bad, also I noticed it plays better when it is in temperature... . Thanks to everybody!
