Thanks to all,

The mod 21 part 1 is completed. Have replaced op amp in the part 2 but not the caps because I have had to order from uk. Can I use the tc-7510 as it is until I replace the caps or do I have to wait until all the mod is completed?

p.s. Is the snow as bad as they say over there?? its 22 degress in Cyprus ( i dont smoke but i like the shades. can we have a non smoking smiley with shades please?).
