Listening to McCoy Tyner, NPR Jazz Profiles https://www.npr.org/2020/03/06/812954365/mccoy-tyner-the-pianist

Land of Giants, and then a little more McCoy/Bobby collaborations.

Made good progress this weekend testing the PSU main board and the GRHVxxx. Everything tested works as designed. The LED has a cool feature - it blinks at power on till the timed delay kicks in then the B+/B- are turned on and the LED stays on constantly. Photoed is my test setup powering my electrostatic CFA. GRHVxxx set up for 339VDC rails intended for my SRX Plus. The current draw with the CFA is quite low and over the 4+ hours, the regulated voltages were rock stable and temperature rise was minimal. I hand-soldered everything including all SMD parts Waiting to hear back on the quote for assembled GRHVxxx board. Should have more to share this coming week.

Finally found a good link to the full two-hour Cure set at Glastonbury last year. Obviously highly recommended if you have the time. Imagine having this catalog to rip through?

Nice job pulling this together Michael

Decided finally to get some iems but I have been out of the loop for some time, so not sure if JH13/16 are still the thing to get or there's new king in town. You guys know what's up or just settled with the JH and never looked back ?

Yesterday I managed to escape from work for the day and go enjoy the outdoors with some coworkers.

Kevin James is killing it, lately.

RIP McCoy Tyner. The Coltrane Quartet ❤️.

Glad you like it. Here are some more: The RCA sockets all soldered and hopefully all the correct wires went to the right spots... The PowerKon is a tight squeeze and required some cutting of the support bar next to it but it went better than expected. I still need to install two 392K resistors on the PRE OUT1 sockets as that's how this unit was configured. 100nf/1000V caps added to the B+ line right on the sockets. This is what we do on the most current Stax amps and given the rather basic PSU design at hand here it makes sense. I also used the empty tabs on the sockets to install a voltage divider for the Pro bias. The B+ is around 640-650VDC so a 10% decrease is needed to get 580V and 22K/220K does that perfectly. I also tweaked the normal bias voltage divider so that it now outputs 230V instead of the stock 200V. Both outputs have a 100nf cap between the divider and 5M ballast resistor.
