My vwn qrp and 830 linear

At last i decided to correct my OLD vwn qrp and irf830 linear. i succeeded in qrp, it is working fine. but fellow hams hesitate to try hard to catch my small signal. this means i need power amplifier, hope it will be fine with irf 830. i searched i found my old linear box. now problem is with the tank coil, i lost the irf 830 circuit, i dont know dimension of the tank coil. mmmmmm,
