Kent 6630 Preamp

[Axldeziak]

Layout is for the preamp section of a Kent 6630 amplifier.

The original transistor is a 2sk17. InterFET made their own version, the IFN17. 2N3819 is labeled as "comparable" according to several tech sheets I found.
Also listed on the schematic as a substitute was the HEP801 whose equivalent is NTE312 as best I can tell.
