An extremely good and very cheap upgrade for the 405-1 is to replace the LM301A with TL071 op amps. The LM301a's are socketed, so the change is easy.

Weekend Bump
The TL071 is itself a pretty basic op amp. The OPA134 is much better. http://www.ti.com/product/OPA134#

Lovely amp Nick, surprised it's still here .... Bargain.
Future classic, and prices rising steadily.

Price reduced to £215. (Anyone know how I can edit my post to change the price?)
