In the new forum software each post has a link in its title, you can copy those to jump to a specific post. For example, this points to your regulated heater PSU board on the previous page of this thread: http://www.groupdiy.com/index.php?topic=28274.msg371412#msg371412 (or: as an embedded text link).

[still coming to grips with SMF, and still working on an autoforwarder for old links]

can someone confirm if this 12 position switch for GAIN & THRESHOLD would work, thanks.

C4D0212S (shorting) or C4D0212N (non shorting)?

JDB, thanks a lot

glide, take the shorting switch

hi glide 1

i was thinking of thoses too...

did you get a quote for them ?

Hi,

one question on the heater psu-pcb:

Where do I hook up that board?

Just put it between the psu-pcb and PoorMan-pcb?

Or right behind the heater rectifier?

Or right behind the torodial 9V/6A output?

Is R15 still needed or can it be let out or bridged?

Thank you!

Greg

They are roughly $20 US from farnell. But now i see they do not have the shorting type as recommended by volker. The hunt continues....

i'm alos searching for 15K double pots...

hopefully, i didn't have a lot of remaining hairs on my head... i wont regret them

Hello,

Or right behind the heater rectifier?

Sorry,dumb question. Found the schems and everything is clear now!

one is for the audio PCB and the other for the PSU PCB

For whatever it's worth, I pulled a 5687 off of a PM660 circuit board and compared the voltage change.  4A unregulated filament supply feeding this 2.6A card.  Voltage change from loss of one 0.9A filament was 0.15V.

this underlines that regulated heaters are not necessary or dangerous
thanks for the test

Thanks, your test prooves me I was wrong !!! Hopefully !!!  ;D

Heatsinks

does anyone have Farnell codes for the following heatsinks:

for Q1 - board
for IC1 and IC2 - PSU

thanks in advance.

glide 1

Edited: Found them

Farnell codes

4 x 1368058 - 2 for IC1 and IC2 PSU and 1 for each board (Q1)
2 x 1319813 - for Q4 and Q5

i find almost everything at Banzaieffects.com

search is easyer, less references... it saves a lot lot of time !
sometimes it's a little bit more expensive but... time is money


here my order :

i took the resistors and the few things remainning at farnell.

I ordered tube Porcelain sockets from Tube Depot - the package says they're Porcelain, but they sure as hell look and feel a lot like plastic...anyone else get these?  Did they mess up?  Isn't porcelain and ceramic supposed to be pretty much the same thing??

Thanks,
Sig

Heres mine with the "bluebird pimp psychedelic mod" ;D ;D

one more for the inside....before the addition of the 6ba6 GR tubes...

cool layout.  link switch?  or permanent stereo?

bluebird,

Nice... but what the hell is that GIGANTIC RESISTOR ? 

That thing is freakin HUGH.... WOW!

Did you buy that on purpose? I have the recommended 50 watt's & they're no bigger than half a finger.

Holly cow that's big... whoa.
