Hey, did you try rolling those tubes? I have the same amp and have been tempted to try something similar. I actually had the same questions as you regarding just changing the ones you highlighted. let me know!
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!
