wel after soldering and trying many different things to my zen kit ,i found it time for a complete rebuild ,and i wanted to build it like a tank ,all value,s are the same as on the schematics of the zen cs ,de oversized resistors are arecol ,i got all the parts from a army electronical surplus store ,the condentsators are rusian pio ,s 0,22 uf 1000volts ,these gave a real improvement in the sound ,the tubes are voskod 6n1p ev 1970 production as a driver and 6n15p ev [sv83] as output tubes a 1960,s svetlana 5u4[sint petersburg build ] as rectifier the bigest improvement in comparesy with the original zen kit where the pio condensators ,the hazen grid modification , the led biasing the rest will just last for a lifetime because of the oversizing the power suply was changed because we use 230v here in the netherlands , grtz ko
