Carmen Ghia clone Finished!

After 9 months worth of work on and off, I finally finished building a Dr. Z Carmen Ghia clone. I built it from the old Hammond AO-35 reverb amp, given to me by Ron Ashcraft back on Monday, May 12, 2008. Building the cabinet took more time, effort, and money, than did modifying the A0-35 circuit. I took lots of photos of the entire process. I will put them all out on a photo dump in the future. The amp sounds great but has more gain than I need around the house, so I've swapped the phase inverter tube from a 12AX7 to a 12AT7. The result is a little more clean headroom with a little less noise.

I recently built an 18 watt Lite IIb using a Hammond AO-43 chassis, iron and scavenged parts, and now I've caught the amp building bug.

I just picked up an AO-35 with the intent of making a CG clone, and would love to see/hear more about yours, as well as sound clips. Your build looks pretty sharp. What sort of heat shielding did you use in the cabinet?
