Yep, here we are again, reversing the work of a Kobbler. This time a Johnson Valiant Ham transmitter. Recently purchased at a Hamfest with the report of A-ok operation. Well, not so. On the outside it looks great, inside a different story. Butcher city at the hands of a Kobbler. The new owner brought it to me for a check up & repair. Everything can be fixed with time plus money. However, you have to evaluate the value vrs repair cost. The bonus was, I could still demonstrate installation of my PTT module K1. A great addition to the Valiant, enhancing switching plus safety. There will be a part 2 soon following updates from the new owner. Stay tuned! Update, I checked the tube data for the 866 and 3B28, their filaments are 2.5vac! The transformer may be OK, I just thought is was suppose to be 5vac, May be a d-lab bo bo! Will cover in part 2
