[QUOTE="Ampdog, post: 742713, member: 144"] .... but keep them safe somewhere! For possible use with another amplifier (you or someone else asked), they only work well into a high impedance input. They were designed specifically for the Quad II, so not poor design in that sense. I use them with one of my own power amps, taking that into account. Higher value caps for KT66 cathode bypass is not a problem - rated voltage is simply a maximum for the capacitor. It does not matter if used at lower voltage. 3300?F 63V would be physically big, so to repeat, take care to mount them away from the hot resistor. There should still be space. P.S: It could be checked whether or not someone has already modified the pre-amp! If you have time and want to take the trouble, post a photo of the top and underside of the -22 (cover removed of course!). The necessary changes will be immediately obvious. [/QUOTE]
