HC Bike/Cycling Thread
When I have to do those distances, I always get nervous. I guess it's normal. In the islands we make those distances but you never have "flat" areas so you have to go reserving for the next mountain pass. I think the best thing if you are insecure is to get into a group whose rhythm is similar to yours and keep a steady but affordable rhythm from the beginning. Does the route you have to do have a lot of elevation?

HC Bike/Cycling Thread
Thanks!!! No, I haven´t it. Normally we make the return by bike as well and the speeds we reach usually reach up to 80Km/h in some places (at the exit of the town of Teror for example). Yesterday when the road was cut by the race we got off in the team's bus. La volata

I wish the slopes here were so soft. ? Garmin is an American company … it is they who should be clarified with their software ?

Megatron Electrostatic Headphone Amplifier
Sorry Jim I means R21K

Thanks Jim for explanation Changed R11 for 1.65K and I had around 245~250vDC in all plates. I was not happy and I tried with 1.5K, now I have 235~240vDC in all plates with 1mA plate current. So I guess that now is more correct. Right? Now I need to change R21 because I have 290vDC and I would like to have all correct voltaje.

Thank you. All the tips are well received of course. Okay, last night I was also thinking about lowering R11even more but I don´t know until what value I can lower it. Maybe 1K ?... I have right now is 1.95K so I'm going to try to lower this value up to 1.5K easily. I'm thinking about Jim's comment about the total value of R11 + R12. Do I have to compensate R12 obligatorily? On the other hand, change R12 you say that should not significantly affect the plate voltage.

Megatron Electrostatic Headphone Amplifier
I made the mod. Modify R6 and R7 at the same time as R11and R23 with the values indicated by Mwl. My data are now: 12AX7 volt plate: 270vDC Voltage Before R11: 12.7vDC and between R11 and R12: 11.7vDC I have not modified the resistance that manages B + 300vDC but now it is at 290vDC. Should I change the value of the resistance to get to 300vDC or can I leave it like this? I need some time to assess everything but in principle everything looks good.

And now what did you do TODAY?

I´m not sure... Go out with my team to do a few kilometres on bike and you will see them like that "sport is health" is a lie. Oh God! This thread is a torture! ???

The Multi Amp aka Dynalo Mk2
I only have ebay regulators. They look good and with 20Vdc AND WITHOUT LOAD they worked correctly (as any LM3X7 would do) but I have not yet tested them in any project. I had thought to use them in a phono preamp (the VSPS) but finally they didn´t work because the size of the preamp's pcb is very small.
