Let's build B1 Triode quick prototype before use of superb Papa boards.
Bigins with PSU filtering now and have one question :
do +F is connected to 270R or not ?
No dot connection point on the first schematic version

 

[Dennis Hui]

I think there should be a dot.

 

[Soundhappy]

Thanks and kudos Dennis 🙂
I do check and report +F and +R voltage's

 

[Soundhappy]

SMPS 24VDC + filtering : +R = 9.2V and +F = 22.5V
it's without anything else connected. All OK ? 🙂
The next step is build audio path circuit

@ Gentleman's

How much is minimal resistors tolerance 5% , 1% or 0.1% for this preamp ?

 

[Zen Mod]

no tolerance!

 

[Nelson Pass]

I use 1% unless I'm trying to land a probe on Mars or make RIAA EQ.

So it looks like my freebie boards are pretty much desired offshore.

Santa is not going to spend his holiday filling out customs forms.

Who wants to step up and handle the distribution?

Papa, I am willing to help but based in Singapore. Will be in New York in 2 weeks time, if you send me the boards in the US, I will redistribute them via Singapore if everyone is ok with that.

 

[Dennis Hui]

If no one in the US is available then I can volunteer. (Though it
will still require one custom form. 🙂 )

Cheers,
Dennis

Edit: Just noticed Ed's reply, which should be more convenient for Papa.

Yeah, we can’t trouble Santa Pass too much. I don’t think the shipping costs will be too crazy from Singapore, the only downside is it will be post Xmas. Sorry.

Sure I’ll take one if one is available. My next project can be a pre amp for sure.

I’ll be out of town until Jan 2nd and could do the shipping the following Saturday.
