I think Stan was talking about these types though:

About 11mm high including the leads.

There are some SMD types available as well:

Any ideas where I can get black gate capacitors, for the mod 21 part one, and that they post internationally – I cant find any on ebay. Apparently they are the best to use, or, will any make do the job just as well?
Thanks

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?).

Go-ahead and use it, see how it sounds then replace the caps and see what difference there is....all part of the fun!

Would the MOD21 upgrade be applicable to the 7520?

i.e. opamp to the LM4562 and the caps to Blackgates etc?

**Ali Tait** · 06-02-2009, 18:59

I'm sure Stan will reply,but AFAIK,no,the output stage is different so MOD 21 does not apply.
