Hello
Some useful info.
 
Just receive ALPS RK27 Terminal PCB Board for Bijou volume control.
 
http://www.ebay.com/itm/171258426056?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
 
Nice price, quality and fast delivery.
 
Photo with RK27 (I solder RK27 on opposite PCB side for some reason)

 
 
-- Regards, Victor
 
P.S.
Be carefully!
This PCB adapter have a common ground between L and R.
So ground loop available! Probably I will do some works with Dremel tool for splitting ground on this PCB.
 
After some thinking I decide NOT use this adapter for Bijou.

Hello,
 
Any noise issues with LED`s mounted on AMP boards?
 
Or better to use separate full-wave rectifier (with 100-1000 uF capacitor) connected with heater 6.3V?

Victor, I haven't seen anything specific about having the LEDs on the amp boards.  That would be a good question for runeight (Alex), however.  Most builds, if done correctly, seem to be very quiet.

Hello,
Thank you for the answer.
Will test with on-board LED circuit first.

Victor, FWIW I chose to install LED's under the power supply and amp tube sockets using the heater for power. No issues whatsoever.

Hello,
Thank you Balderon.
As I understand you place LED`s in central hole of tube socket`s for illumination.

Victor - nice photos.  Good, clean work!  I see you socketed R2.  You must be thinking about the Regal mods :wink:
 
Yes, many people do put LEDs under their tubes for illumination.  Just don't use the LEDs that automatically scroll through the colors: Someone did that a few years back - he said it made him crazy in under five minutes!

Hello,
Regal mods was used from beginning.
No, no...
I`m very old for using multicolor LED`s.

Only one orange LED will be used on front panel.
 
Just receive Bijou labels.
2 layer plastic (black+silver) laser engraved
 

 
No idea which label place on the case ... I like all :)
 
Funny "warning" stickers (hand painted - DIY)

Cool labels, Victor!  You wont know which one to use until you get the front panel mostly done (if you ask me).  Where did you get them done?
 
Where do you plan to place the high voltage warnings?  :)  Fun stuff.

Thanks Bhjazz.
I order "Bijou" labels at local company that provide laser cutting.
Like that http://www.ponoko.com/laser-cutting
I think google can help you find company near you.
 
But really my labels have a "cheap" appearance (I spent only 3$ for 5 labels)
Probably I will do experiment with Dremel tools and aluminum plate (engraving)
 
Skulls labels.... I think will be inside case.
