well done @acefactory -- here is a pic to accompany your excellent description
so the tubes op wants to roll are three of the four middle ones (leaving aside the one single middle one with the white spring loaded tube damper/cage)
Tube Rolling | Luxman CL-38uc
Hey guys!
Was wondering if I could get your advise about tube rolling on a Luxman CL-38uc.
http://www.luxman.com/product/detail.php?id=27
I’m trying to avoid having to change all Tubes (I want to change them for NOS Tubes).
Since I won’t be using Phono or Tone Controls.
I will just be using the Balance Line In and Line 1/2 Out.
From what I can tell from the schematic (see below) I only would need to change the ones enclosed in green.
Here are the schematics for the CL-38uc Pre-Amp per Luxman: https://drive.google.com/file/d/1pzkwm9U4JIDqbYN-KUmwtvVAFiipUlOG/view?usp=share_link
My questions
- Is my assumption accurate? Or do I need to change other ones?
- Can I use other type of tubes in place of the 12AU/ECC82?
For example I have plenty of ECC83s/12AX7 If so, is there any precautions I need to be aware of?
Any help is appreciated,
Thanks!

Thank you so much @acefactory ! you just saved me ton of time trying to figure that out! :) ... I'll report back on how the tube rolling goes, will try a set of Telefunken and Mazda tubes. @jjss49 thanks for the picture, comments and your initial remarks regarding tube differences. You are absolutely right, better to stick with 12AU tubes in this case as intended (that's what I ended up doing). |
