Re: TAD Range King schematic [traced]

From looking at the photos, R1 looks like 4M7 to me (yellow-violet-black-yellow-brown) but i could be wrong. Indeed, I measured R1 with 470k an R2 with 2M2. I ran a simulation with the new values which confirm the read voltage values. Thanks Manfred but here is another one photo, R2 is still questi...

It's option, in this case not in use.

Thanks to mirosol photos http://www.freestompboxes.org/viewtopic.php?f=7&t=28913 and some others from the internet, I drew my first version of this schematic. Some values missing.

This pcb founded in the Solo Dallas website is probably one prototype, R2, C2 and other missing components just apears in the comercial units.
OK, I made components drawing using this picture.

Re: Solo Dallas - SVDS Replica [traced]

I made some my drawing for this project but there is some incongruity with this PCB picture and schematic. There is no R2 C2 components on this PCB, also I traced only from top side and I don't have some values. Work is still in process so the corrections are on the way.

Right, high voltage is about 203 V and heater voltage is DC 6.3V stabilized. Only one half of tube used, I don't like that style of unusing half tube. It certainly could be used since the tone is not something striking.
