im about 1/2 way through my '34 84b. got the last cap i needed yesterday. one other website advised using dap concrete joint tar to fill the blocks, originally close but yuck! i dont plan on doing anything till the set is ready to go back in its cabinet any way.i was tempted to leave them empty, but because of the high voltages involved i was concerned that dust and such may be a problem, i briefly considered candle wax and 3140 rtv.what do you fella's advise???
