2 pics of the progress of my Turbo (liquid cooled tubes, gold trannies and more, way better then the D-AOC ) D-OAC beast!
Still waiting for the mains trafo, optics, potmeters and the solen but it allready looking like a real one.
Frontpanel is done with lasertran (first time) and i'm quite happy with the result tough i made a scratch (dammit) on the panel.

:grin: yes, keep them coming :thumb: :thumb: :thumb:
you have made a realy nice looking D-OAC :green:
I like all your individual frontpannel ideas. :thumb:

[quote author="[silent:arts]"]for the Meter:
the circuit is taken from the LA2A
(which uses a VU Meter)
btw, there is a 3K9 resistor needed in series with the VU which is not on the PCB
(since I wanted to have a switchable "Gain Reduction" / Output VU)

some comments from Keith:

and how to calibrate it:

(R25 = R126 & R226 in the D-AOC)[/quote]


what about the jlm vu buffer?

"It turns cheap dc type VU meters into working VU meters."

(trying to find vu meters to use in a 3u unit...)

 

[[silent:arts]]

you can use the jlm vu buffer.
we have the PSU3 to power it :green:

 

[EEMO1]

i guess im going to get a couple of those buffers just in case.

i bought 2 boxes of meters a year ago. still have plenty left...

Hey guys if you're still shopping for parts like me :grin:

You can find a lot (vactrol, wima caps, tube sockets, solen fast caps etc...) from http://www.banzaieffects.com/

They are located in germany, prices are good (for ex. solen 10uf/630v is 1,75 euro cheaper than dasmusikding).

they're just a bit slow at processing your order (4/5 days) but for the rest they have a very good service ( I ordered most of my g9 parts from them)

hope this will help you,

cheers,

nicolas

North American Guys,

My custom Edcor power transformer arrived today. It is beautiful! :grin: Smells absolutely delicious too. Time warp to building model cars and using Testor's enamel paint. But I digress.

The unit is clearly labeled and very well finished. I will post pictures later tonight when I get home to my camera. :thumb:

Hey guys I just wanted to let you know I had my Power transformer built by
Heyboer Transformers, they also built my 10K:600 output transformers too.

http://heyboertransformers.com/index.shtml

The prices aren't as good as Edcor but the quality is pretty damn amazing and the output transformers is awesome.

65.00 for the power.
85.00 for the output.

They are a really cool "mom and pop" shop, nice people and easy to do business with. Its easy, you email them with your request, they email you a price, you approve. They will snail-mail you an invoice and you can pay via paypal (+3%) or send a check. turnaround time is about 1 to 2 weeks.

Where in the US, can I get the 10uF Solen Fast Caps?

I found them at parts express but the voltage is only 400v. (But 600v is specified on the PCB overlay.)

Thanks for any tips.

 

[[silent:arts]]

Kato, 400V is ok

 

[dissonantstring]

hi kato,
you can get 10uF / 630V Solen poly caps at Antique Electronics:
https://secure.tubesandmore.com/
$6.50 each.
-grant

 

[kato]

Thanks friends!!
I guess if the 10uF doesn't see > 400v I should just use that to avoid the hugeness of a 600v cap. (at least I imagine it will be huge.)

BTW - I bought a bunch of extra wimas to get a volume discount. If anyone is interested in saving a few bucks, let me know. You can glom onto my mini-"group buy."

 

[[silent:arts]]

added a link to the first post for all the US/north americans since there are still questions where to buy what.
MikoKensington did all the work for you here:

BTW Tube Depot doesn't have the 39k 2w. They have a 33k and a 47k. Is one of those close enough or should I look elsewhere?

I ordered a 33K and a 6.2K and put them in series.
