we worked on a V4 a while back, now we have a V4b in the house,
the "b" probably means good for bass, which it is due to the nice chunk of hernia iron,
we are going with loose caps instead of the 3 ea. forty dollar cans, we can get some Nichys in there for about twenty bucks,
lets knock out the plate and screen filters on a piece of moth proof cedar, tie warp and hot glue gun, no terminals required,
increase voltage divider Resistance for less heat>
