Hi everyone, new to this forum.
Just like some information on the AI L200 pre amp
what valves are used.
Below should be a picture of the pre amp.
There are only four valves.
Starting from the left is a 12AX7WX sovtek valve
The front one of the middle pair is a ECC83 Telefunken.
The one at the back is also a ECC83 12AX7 Mullard.
The far right is a 12AU7WA cv4003 ( could be a brimar brand ?)
Does anyone know if this is correct? Should the ECC83’s be a matched pair ?
I’ve been using this preamp for the last 18 months will very good sounds.
The System is L200pre, quad 306 power, speakers are markaudio cesti B’s
The main source is vinyl, funk firm LSD turntable fitted with a koetsu black cartridge, then a hagerman valve phone stage.
Would like to look into tube rolling on this pre, if anyone has any advice.
Thanks Steve
