Without internet for a while. Neighbors giant oak tree fell root ball and all skimmed house, did some damage. Ripped off power and cable wiring and blocked driveway. Other than that, it was perfect day. NOT!!

I prepared this photo tutorial to guide you through the bridge snubbers on these amplifiers. PL400 amplifiers are easy as there is plenty of clearance. The PL700 amplifiers have less clearance all around so this provides the technique to be successful. Hope it helps you out.

May it be a good 2023 for all of you...cheers!

I have long, long thought of offering a control board that saved builders time, reduced assembly errors and perhaps made the control board smaller by moving to SMT technology for all the small signal resistors, transistors, diodes, etc. which comprise the large majority of the components on the...

Hopefully this will be helpful to WOPL builders. This is a build conducted with all new materials except the transformer, meters, faceplate and 8 fin heatsinks which have been reused. This PL400 Backplane build utilizes NTE192 bias transistors, not the usual 2N5088 transistors we all use...
