    A Very Compact Hybrid Amp

    Quote: Would you say it was a difficult build? Not exceedingly difficult: the process of assembly was similar to any other through-hole board. However, the density of parts on this board is significantly higher than in most amplifiers, which leaves out several luxuries present in...

    NOS PCC88 / 7DJ8 which rebrand? Win a pair. :)

    The use of a flying saucer getter and the style of the mica supports suggests Soviet manufacture- a reboxed and relabeled 6n23p? I'm going to guess from the Reflektor and not Kaluga factory as the plate ends appear to be closed and not "pi-shaped".

They seem to have a different package than the 2sk389, and the specs are 'improved' over the older part. I don't know enough to...

    Good, cheap pots

    got a load of these from the goldmine today- very nice construction, and a great deal obviously. I'm wondering if these can be disassembled and recombined into 4-gang or greater? I also dropped six dollars on the G9231 'super electronic surprise box'. Recommendation: everybody needs to try...
