Scratch built phono stage

[Wardsweb]

Here is my latest project. A three gain stage (12AT7 - 12AX7 - 12AT7) with passive RIAA phono pre.

Here is the working side with all the fun bits.

Here is a picture of the chassis before I did the tube cut outs.

Here I have cutout to recess the transformer up into the transformer cover.

OK, obvious question: so where did you get the chassis and the turret strips?

The chassis is from China off Ebay. I asked for one without holes already drilled, so I could do my own custom layout. I used a rotary Alps on/off switch in place of the originally designed preamp volume pot.

The turret strips are from AES: https://www.tubesandmore.com

Beautiful work.

What do you estimate the cost to have been?
