Who helps me finding a chinese? Had a chat today with the Staxmafia boss, he didn't do the names, but indicated that some time ago, a chinese was selling this modded set with stax plug... Does someone want to be a spy? Or if you do not wanna do the name, also some hint about getting to him would be appreciated? Thanks a lot 😁

surprisingly on something like a 727, the peaks are already clipped at moderate volumes. so this will let all the wonderful dynamics thru. and damaging you hearing, definitely.

Ordered a couple of tubes last week. The USPS has them circling the country. They started out in Chicago, came to Memphis distribution center, went to Mobile, then Nashville, back to Memphis, down to Jackson Mississippi. They are back in Memphis now. I live outside of Memphis. How does this keep happening?

Though running it close to max bias will probably damage your hearing.

max voltage swing is 4 x bias. so 580 x 4. the amp does loose about 20 volts of voltage swing, so 600 is a nice number. same voltage the koss uses. also the rating on the pnp transistor. could cut the voltage to 550v for a bit more margin.

Wow! But just for my understanding, this is the limit after which damage to earspeakers can occur, right? I mean, so much power is really needed to drive the most demanding e-stats? Or is it thought as an exercise of pushing it to the boundaries ?

It looks like Western Digital is having serious problems with its older SMR (Shingled Magnetic Recording) hard drives. High failure rates of Western Digital Blue and Red drives of 2-6TB have been reported: https://www.tomshardware.com/pc-components/hdds/wd-launches-investigation-into-problems-with-its-smr-hard-drives-the-same-drives-that-got-wd-sued-in-2021-now-reporting-failure-rates-due-to-fundamental-flaws

Finished it last night. Pretty good.

Shostakovich: Symphony No. 5 in D Minor, Op. 47 by Howard Mitchell (1959) https://album.link/trxprptjq5zr7 Example: Noise floor is a little high (hiss), but it made up for by getting very loud and being a great performance.

I was lucky enough to meet Prunella Scales around 20 years ago. She gave an acting masterclass to our local pro theatre company, Creation Theatre, that for some reason we got invited to. She was very nice, and was really tiny.

Timothy West - also a great actor of stage and screen - predeceased his wife Prunella aged 90 in late 2024. https://en.wikipedia.org/wiki/Timothy_West

Would swapping out the rolling casters with footers improve the sound too?

Removed the grill which removed a "veil" from midrange 😆 and had to rework the crossover and physical alignment of the supertweeter, but yeah, I'm beginning to think the speaker angle was already a solved issue in the 1950's and 60's..

power supply schematic updated. amp board updated. circlotronpsupdated.pdf kgsshvcarbonv6.1c3cs - CADCAM.ZIP

Seems simmconn reads shematics. Regarding Q12, schematics and gerbers don't match, I think.

Maybe I didn't give them a fair shake back in the day...

I was just pointing out, as how Q12 is connected today, it’s not doing what it is supposed to do. The output should be connected to gate instead. I remember last time you recommended TTC004B as a replacement for the PZTA42 (different package). We just need something with a flat hfe-Ic curve to, say >100ma at VCE=10V.

q12 is the current limit. so if the amp board shorts, at least the power supply will not explode. what do you want me to replace the pzta part with? remember 20+ma
