    There is more to this lack of sales. Tesla is eating their lunch. The average time for an Ev in high production is 60 man hours Tesla is 43 No wonder they can discount below others profit level. Volkswagen is in a serious Delma with these EV production world wide, they generate 40% of their...

    That is a great idea Mark the horse’s mouth is the captain , Bob Carver we’ve had a few interesting discussions including Casode transistor configuration for amps. Bob and my brother did a lot of business back in the 70’s and he helped develope Bob’s amp for the PA market, not so much in design...

    1500va still more than enough and it will be interesting in what the toroidal transformers produce compared to traditional wind I’m setting out to build a dual mono using four toroidal 650va and 80 volt each leg common tap.so extracting 5ish watts it’s something Lee , Pery and I have started...

    Oh no The phase linears are 2000va transformers. I got that from the horses mouth

    This will easily match the 700 We’ll be following you Mark I’m a bit jealous of you getting to pioneer this amp and I am sure it is in good hands with you at the helm

    Thanks Mark I guess I don’t quite get it Combined 425 rail voltage should yield about 1540 watts per channel not 500. The dual 500 secondary out put is 87 volt which translates to 120 volt per rail or 240 combined anyway no worries and hope your build goes fast. We‘ll be following you

    Great to see this project finally underway mark what rail voltage will this be if you using this “The main toroidal transformer is rated at 1500VA at 475V”.

    Spaceship launched

    It looks like the booster failed to light all necessary engines for the burn back after flipping causing control of it lost so they quickly blew it up. No idea what happened to starship. It bacicly made it to power down point. Also many tiles were lost durning its 8 minute ride. I realy think...

    Yup. 146 klm up in the air with no engines failure. who knows who pressed the button. The FAA has a button as well. How’s that for a conspiracy theory

    Exactly but what a pain. I’ve gone to sequencers . At least I know I’m not the only one with this to deal with.
