Mike, I need some advice on what to use to replace the glue-soaked cloth tape. It needs to fix the turns and provide a high degree of insulation. I could use ordinary plastic tape but it may suffer f
Mike, Andy is spot on as for normal operating conditions, but if Murphy has his way (as he usually does) there are a couple of scenarios where the 320V peak can be greatly exceeded. One would be a ne
Further to my report on the failed combiner/output transformer in my Decca QRO Tx, I have dismantled the transformer. The really good news is that the huge (85mm dia) ferrite pot was not glued at all
http://www.kaptontape.com/ I think this is the 'righ stuff' for transformer construction , a dupont product that has high electrical and physical strength . and low dielectric loss G.. Further to my
Its teh output transformer, so even at the 1kW level voltage won't be all that high. Assuming 50 ohms, only 320V or so peak. ANd any heatshrink sleeve will withstand that. The fact that the orig
Hi Mike, You'll likely be able to get some flame retardant cambric sleeving at a motor repair/rewind shop. They use it all the time to bring out the enamel covered wire to the terminal blocks. I have
