Hey guys...

I'm thinking about building a tubed line stage - pretty much decided on an Aikido, using the 9-pin PCB (http://glass-ware.stores.yahoo.net/aik9pinsterk.html). I'd like to go with a tube rectified PS. I have no doubts in my ability to assemble the PCB, it's just the putting-everything-together stage that's confusing me :)

1) Would this power supply kit work for the Aikido? (http://www.stf-electronics.com/Page0015.Html) Not being able to run 12V heater tubes is no problem for me, there's enough 6.3V ones to keep me busy for a while. I'm also not sure of whether AC for the heaters is the right way to go, but DC seems like it'd add to the complexity.

2) I don't have a lot of experience with metalworking...is there a way to get chassis cutouts looking good if you don't have a drill press? I know it has nothing to do with how it sounds, but - it's one of those things that'd annoy me :D I think I may have to borrow a Unibit from someone.

Thanks in advance.

Hi Gregg, can you post a link (I just looked and did not see them)? I still have not used those Aikido boards I got from you years back so I may be able to use power supply boards too.

Hi KG4NEL, from the Aikido manual
Quote:
6V Heater Power Supply Although designed for a 12V power supply, a 6V heater power supply can be used with the PCB, as long as all the tubes used have 6.3V heaters

That tube power supply kit is 320VDC @ 80 mA and 6.3VAC @ 1.5A. So yes, that tube power supply kit can be used provided the tubes you select have a combined heater draw of less than 1.5A. 80mA on the B+ will be plenty for a preamp.

Gregg,

Please post a link. I have an unfinished Aikido, and I might be interested in building a tube based supply for.

Thanks

Alan

Hi guys,

Terribly sorry, I forgot that they aren't listed on my site :blush:

Info here:
http://www.diyaudio.com/forums/showthre ... wer+supply

I charge exact postage + $0.50 for the bubble envelope.

Double check for quantity on hand... I get rushes where they sit and sit, then *poof*, I sell 20 in one shot :o

I thought I sold something to you before when I joined here ;)
(I don't keep detailed records on my box in case I get hacked)

Cheers!

I have one of these boards for my Aikido and it works great. Very quiet and simple to stuff...
