Thanks a lot

Got my boards and resistors today.
Thank you very much Tea-Bag.

Just like to clarify that the relay diodes (1N4001) are non critical and I can use 11DQ10s, UF4007s I have lying around right?

Got my boards and resistors yesterday.
Really well done.

Thanks a lot

P.S.: can i ask for the post# in which to find the latest schematics and BOM?

 

[Tea-Bag]

my blog blips should have all that attached.

Still waiting for my boards...
I was probably on the second round.

 

[Tea-Bag]

Tasso,
you show up as shipped on my list.
Last time it took up to a month (a some after) to get there boards. Hold in there.

I promise to be patient

Boards received, they look great. This is definitely going to be easier than point to point wiring! Thanks, Tea Bag, and others, for a great project.

I am currently out of PRP and Takman resistors. I might be able to order more of them, but the Tak's would have to be at at least 1/2 watt in the 220k section (read more $). If people really want these I will order maybe 5-10 sets of each. I still have about 70 boards total left. Once I get a bit lower, I will bleed the stock out slower if original buyers haven't gotten their packages, so I don't run out if theirs gets lost.

Based on last time, most had arrived at the 4 week mark.

Of course I can order more boards, I was hoping to have enough to put off ordering more until June or so, if demand is still there for it.

Hi Tea-bag, I have received the PCBs and resistors in excellent condition. Thank you, you done the great job.

Hi everybody,

time ago I bought a finished BoZ, I wondering if it is possible to transform it in a DCB1.

The 25K Alps pot seems to fits, but the trafo is 2x30 Volts! Becouse of enough room in the case I would also add an headphone amp.

Any insight?

Cheers
Peppe

 

[Tea-Bag]

certainly will need to ditch the transformer, or find some way to roll down the voltage a bit.

Ok, so maybe is better to add a trafo for the B1.

I am searching for an headphone amp pcb/kit now. I need the B1 feed my active desktop speakers and a solution fo my high impedence headphone too...
