Rectifier diodes

[Tony Allgood]

Hello,

Some while ago somebody was talking about diodes they could use an op-amp
based full wave rectifier. I use 1N4148s, but are these good for rectifying
triangle waves for frequency multiplication at audio frequencies. I am
hoping to try some out this week. How about the op-amps? Will the trusty
TL07X do, or should I go for OP-42s and the like? Anyone built a good
rectifier that minimises fundamental bleedthrough?
