Well... on the parts search once again... And thanks for the tips on where to find stuff... Got the 1/4” panel bushings from Leeds... Now looking for some 240 volt blowers suitable for 8877 (need 4 blowers) and also something suitable for a pair of 3-500 tubes (need two blowers for them. And they can be 120 vac). Thanks! 73 Jim W7RY
