Re: WAD 300b hum and buzz

Re: KiT/KaT6550 and fuse blowing inrush current

Greg has made some good points. It's easy to spend a few hundred pounds on new tubes or Caps that will eventually need replacing, but a set of quality Tx's are a better long term investment.

Re: Where to from here...?

To do it on the cheap I would just do the boards and box, and get a kick back from supplies for using their transformers in the design etc, so you do not need to hold stock on costly items.

Re: Crossover components rolling ?

I don't know why you would risk destroying 200 tweeter by using under rated capacitor, I would be very stressed at pushing the volume up, the voice coil is very delicate if the cap fails.

Re: Interconnects
