Cheap Chinese 6P3P kit

that it the power feed the input (audio signal) is @ the 100k pot, and the audio out is@ the 2.2 uf on the right side of the schematic
 
One black is center tap of filament, the other is shield layer is center tap of high voltage. It's OK to connect them to GND.

Still can't see the wiring under the 6W 330Ohm resistor. But There's no way to get 920V whatever you do with these transformers, just oddly.
 
Ok Guy's I grounded the - side of the cap's . And then looked and my meter was set to A/C. I switched it to D/C and wow I have 420v D/C just as I should.. Ok one problem fixed now I will press forward LOL its been a long day for me yesterday and I just overlooked the meter setting

Ok after a good night's sleep I'm off to work. Later tonight I'll look at the preamp again and see how far I can get with it. I'm thinking I'm close at this point. as I was looking over the circuit's It looks as if every thing is were it needs to be. I checked it pretty well!! all the cap's and resistors are correct. So I'll give it a test tonight and report back to the board.. Many thanks to all the people that have helped me thus far.. Yes I'm still learning and every day I learn a little more :)
 
Oh my friend, that's great news for me...Just look at the email you sent me yestoday:D

Anyway you worked it out. You can go ahead with the preamp now. I bet the original 6z5p is not bad tube, isn't it? hope you can finish it soon. Be careful when handling HV

Bob, it's up to you, get refund or resend after the package arrive here. I suggest you take John L's suggestion to use air+ground shipping. I am willing to share some of the shipping cost if you choose air+ground shipping method.

Sled, don't know the status of your package. But it's not joke. We had 2 packages to US and one to Sigapore were sent back due to "safty" reason. I don't know what is unsafe in our kit. Maybe the tubes contain some heavy metal that may harmful to humam health?

Hey Ray - I never heard back on my replacement solution. I've e-mailed you privately as well as contact here. This seems to be the only place I can get a reply. Any headway on my replacement kit??

Cheers,
Bob

Hey Kegger...I'm still waiting for My PreAmp Kit, which probably will Never get to me...But, if by any chance It does...What's the Ch Right from the B+ on your Diagram Refer to? Why would it be Fed that way? Thru the 3K...

Just for clarification, this isn't my schematic but the Siliconray preamps schematic.
(I just cleaned it up a bit)

And I just cleaned it up a bit more, with an added "amendment".

--

So I don't have to explain it for everyone I'm starting from grass roots here. ;)

If you follow from the rectifier out for B+, you see 2 330ohm res and those 2 330uf caps,
those are what are called RC stages, resistors in series followed by caps in parallel an are
filters to try an clean the AC that's left from the rectifiers changing the AC to DC voltage.

Anytime you have resistors in series in the supply it needs to be followed by a cap, so you
see that 3rd 330ohm resistor, follow it up top you see it's cap of 22uf, that feeds the 2nd
triodes in the schematic and should feed BOTH channels(that's the amendment), then that
continues on through the 3k res and it's 10uf cap to feed BOTH channels of the First triode.

Kegger THanks for clean the schematic.

Bob, where did you send emails to? I haven't receive your email personally. You can contact me by email to mike@ezpcb.com

I forwarded you the last e-mail I sent you privately. I'd like a new kit sent to me air PLEASE. I can split the difference for the extra air charge just let me know or send me a paypal invoice for the extra charge for air.

Thanks,
Bob
 
Should be soon and some of these amps should get built, pic's posted, and opinions - I'm just hoping.
 
Nothing as of yet? I did check all the voltages and the test points. ALL tested perfect!!!!!! so i put signal though the preamp............ Well I have a lot of HUMM. Crap where do I start? I'm going to walk away from it for a little bit of time. If anyone has a photo of the layout of this beast I would love to see it!! I'm going to do a different layout if I have to, I'm not giving up. But any help is always welcomed
