Just finished up a fun build of a Dynaco ST-35 amplifier. I included some fun stuff including:

• Teflon tube sockets with Beryllium copper contacts
• Ceramic gold plated driver tube sockets
• Mundorf and Obbligato driver board capacitors
• Solen power bypass caps
• Kimber TCSS internal wiring
• Kiwame / Koa Speers carbon film resistors
• Hammond 156R Choke - 56ohms DCR
• Dynakit Parts ST35 BCU (Bias Control Unit)
• Front power switch
• Triode / Ultralinear Switches
• Cardas RCAs and Binding Posts
• C8 power inlet jack with custom C7 power cord
• Custom powdercoat color-scheme
• Alternate fuse holder and placement
• Custom Brass Engravings

Here's a few pics:

Bryan, I really hate to see you suffer with such a bad amp. You can send it to me with the cables you are putting together for me and I will sacrifice myself with it.

very nice-nice colors and details-i like el84's as well as 2a3's-i had a st-35 -i sold it to a guy in france of all places--like you i used mundorfs and quality resisitors etc-but it did not have that classy look that you have captured--howie

Sweet!  I'm jealous.  Makes me want to go out and start up a whole 'nother project.

That's really fantastic work.

Very nice!! What are you going to use for a preamp?

Thanks fellas! Miguel, I think I'm going to have to torture myself with the terrible sound it produces while I finish recabling your cans I'm actually using a rebuilt PAS-3 as the preamp, a match made in heaven if I do say so myself. I built a little shelf for both units to sit on above my work bench.

And here I was thinking I could help you (Bryan), I shall try harder next time.

Beautiful amplifier. I love Dynaco amps. I have a Will Vincent rebuilt ST-70 that just sounds amazing.
