    • He veneered the top and sides of the boards. I felt like I was doing surgery. I covered as much of the veneer as possible while soldering.    I also charged for the autoformers and extra for packing since they were going across the border. I think actual labor was $200 per board.   He’s basically selling for cost of the parts. Pretty good deal from where I’m sitting.  
    • Hi all,    I got a pair of 301-A this weekend- when I got them the tweeter had zero output at all.  They have the KP-3.0B crossover   I took the tweeter and woofer out when I got home and checked continuity of all the drivers and none showed open- the polyswitch showed about 1.5 ohms when I checked it so I think it is working but perhaps has been set off a few times based on what I've read here about resistance going up after they have been triggered?      I then went straight to each driver from the amp at a very low volume and confirmed all of them are outputting, then put it all back together, and now- only the mid has output- no woofer or tweeter output.      I'm quite sure my connections are solid off the crossover, I took a pic of it before and after and also wrote down the connections so it should be the same as it was when I opened the box.    I want to test the crossover, but have never done so and wonder if the caps can be tested in the circuit or do they need to be removed before hand?  From all I've read here the inductors are not going to an issue, and the resistors look fine with no sign of getting hot or scorching     I checked fuses and they are fine- stumped on next step.    I'm not a total idiot but frankly I've never understood crossovers so am in the dark here.    Suggestions?

    • those are BEAUTIFUL... and I bet they sound wonderful.
    • Ever build anything like this before?

They don’t even list the test frequencies anymore, just give you a total power number.    I looked through some of the Chinese built tube amps on Amazon. Same - all you get is a total power spec.
