I have built a direct-coupled Szekeres, no gain stage. The PS gives 24 V DC, this is split by a TLE2426, which is followed by a BUF634 (DIP version). According to the datasheet, the BUF634 can give a 250 mA output surrent. Is that sufficient for the Szekeres? I'm asking because after running peacefully for some time, the amp seems to have fried a BUF634; the voltage was no more split evenly (-16 V and +8 V instead of +12/-12) until I swapped in a spare buffer. Judging by how hot it gets, it seems to draw a whole lot of current
So, should I consider to build something different (or use stacked buffers) to split the voltage?
