Mullard Match QUAD NOS CV4003 12AU7 ECC82 Box Plate tubes

Mullard Match QUAD NOS CV4003 12AU7 ECC82 Box Plate tubes. Low hours of use on my pre-amp under 80 hours of use.

I have family so no longer into audio. The Sound is on the medium mellow - neutral.

If Telefunken is the "standard" sound then these is a bit more warmer.
