 New amp photos
--------------------------------------------------------------------------------
 Here are some photos of the latest amps. This is a combination of 2 heads that I just finished. The one with wrinkletext paint is a Bassman style amp with Mid boost switch, the other is a plexi style with gain boost and master volume. Both are in Mahogany cabinets with red lightup faces. The inside shot is the plexi.

 That is nice craftmanship. Very good looking cabinet and the light just tops it off. It's sweet!

 Do you worry about your future?

Buy a Straub amp, store it for 20 years, bring it in to Sotheby's... and enjoy the rest of your life...

 Thanks guys, glad you like it. I love this hobby!
As for the red light......I use a clear plexi face that I have engraved on the backside(lettering is backwards) I then have LED banks that run off 120v that I mount above the face to backlight it.
As for Hummm.....this one is VERY quiet. When I setup this design(the two seperate boards) I spent about 2 weeks debugging the first one I built. I now have a grounding scheme and parts placement that eliminates noise. The boost switch adds 'rush' noise with the extra gain, but not that much.

Thanks again,
Harry

 Hey Harry

 People order them, and I build them. I do some minor customizing(transformers, woods, caps, rectifiers, light colors......) but basically use 3 circuits with the same chassis configuration.
The bassman style is going to a guy in Wyoming, and the Plexi is going to Peoria IL. I have amps in 8 states now.
It keeps my hobby moving and gives me a reason to build amps. I am working on two new radical designs(my own designs) for new models later this summer, this is the fun part for me.
As for gigging, I include ATA flight cases for them for $150.

 As a matter of fact, I am trying to make all the cabinets the same and not name them.(Ease of manufacturing....) I offer any type of wood people want, but most folks just stick with the standard Mahogany. It is hard, doesn't warp/expand, and looks better with age.
The one head in the photos is a 5F6 type amp, with the mid-boost circuit, annodized/silkscreened chassis, lightup face, Heyboer trannies and mahogany cabinet runs $1100.
Weren't you making amps for folks? I thought I remember you making some plexi heads for people?

 Looks awesome Harry. Do you use a router for your logo work?

 I have a local laser engraver who does the logo work and faceplate engraving for me. It is pricey, but it is the easiest way to do it and looks great.
