Hello. My experience has shown that it is better to make several transformers to service amplifiers. For option T2, I would like to use four transformers. 2х for heating lamps. third for +250v and -260v. fourth for +500 and -500v. I have a question for experts. What currents should be at the transformer output 50 or 100 mA?, in order to hold the load +500v. The same question for voltage +250v. P.S. Sorry if everything is not clear, I use Google translator.

That's about as far as they can take these cars without becoming silhouette racers... you'll see different levels of extreme car building in the various classes of WTAC (a Porsche 968 has done really well). The cars have massive power and aero to achieve record times (RWD, AWD, FWD)... without the restrictions you seen in regular wheel-to-wheel GT racing. In Japan, Tsukuba's track is used for many Time Attack competitions and WTAC has been doing the same in Sydney for years (there was a lot of coverage on the website www.speedhunters.com).

Heather Nova - Breath and Air. Been a huge fan for years, she has an inner passion that I just love. Even though I don't think all her newer music is as strong as much of her earlier work, she still has that passion I love. I FINALLY got to see her live in a small setting, a semi-acoustic set with her brother (who goes by Misha); this was maybe 2-3 years ago, after having 2 different shows cancelled before that. A wonderful experience, got to chat a tiny bit after the show, she is very nice and gracious, really appreciates her fans. Example:

Last night I did the first power-up. I used some very inexpensive 300Bs just in case anything went wrong and to avoid risking the expensive tubes. Balance was actually very normal. About 5 V on one channel and 3 V on the other. But the offset was around –100 V on both channels. I’m guessing this is the “–100 V output” issue you were referring to? Let me know if that matches what you’ve seen. I haven’t had time to swap the cathode resistors yet. Measured Vgk is about –42 V, which is clearly not deep enough. I’ve ordered some 7.5 kΩ resistors, which after calculation should bring Vgk closer to –90 V. Also, for anyone interested, here are the LMQ66430 output voltage setting resistor positions I used on my board: M20-8760542 is a header pin jumper. 1–2: reserved positions 3–4: 6.3 V 5–6: 5 V 7–8: 2.5 V 9–10: 1.5 V Hope this helps anyone planning similar setups.

Crossing Borders by La Serenissima (2025) https://album.link/j4gkqzjvdxptv Example: Not what I expected from the album cover, but a lovely collection of Telemann, Sieber, Durante, Vivaldi, and Brescianello. Very well recorded and performed.

May be worse than that and see below, however the above R4 was $50 more everywhere (including Hiby) for the 3-4 weeks I searched and only lowered on Amazon a few days ago. I did see a SmallRig tripod whose sale price was the same as everywhere else most of the time though. Guess it depends. https://www.theguardian.com/technology/2025/jul/07/amazon-grocery-deliveries-prime-day

Condolences. That's tragic and awful.
