While running 'burn-in' tests on the new power supply yesterday afternoon, we discovered a problem with the 6V6 transmitter which we kit. The transmitter did not want to transmit reliably with 40 meter crystals on 40 meters. We have several solutions in the works. We need to hear from the buyers of these "Remember When" kits so we can send you the latest news and fixes either by email or postcard. More later.....Glenn NN8G
