Conrad-johnson MET1, a vacuumtubed, 6-channel, analog-only preamp I bought several years ago and have improved somewhat.

Original internals with coupling-cap pairs (4uF 'propylene and 0.15uF 'styrene) circled. That 'logpile' of big white caps is five 20uF/600 'propylenes in the first stage of the HV PS.

The three new coupling caps, SoniCap Platinums for the front-L & -R and MultiCap RTX ('styrene) bypassed with Platinums for center.

Jupiter HTs and Platinums in the PS-output stages and a closer view of the 20/600 initial-PS caps.

I REALLY like the sounds of this preamp.
