Here is a schematic and board layout for the DD-30. I build them using Heyboer iron from Toneslut.com. Toneslut's prices are competitive with Hammond. Two can caps were used, 20/20/20/40 and 100/100 from Antique Electronics. For those in the UK who can't get 12bz7s, a 12ax7 will work. However, it may sound buzzy when the power tubes are pushed hard. If that happens, raise the grid resistors of the power tubes from 10k to 47k.
Lead II Lite or L2L
The L2L was designed as a mod to the HO or SEL using the kits and boards supplied by Chris. That is why the output section wasn't finished. The prototype has been built using the SEL output section and came out sounding pretty good but a PP output section could also be used. It does the mean to clean thing almost as well as the DD-30.. The tonestack has changed, as well as minor component values, to make it more down tuned friendly. These changes were underlined in the schematic. Also, the 10k resistor supplying B+ to the first two stages was changed to 1k as originally built. The original schematic will remain posted for reference.

Lead II Lite Schematic
The faceplate files are designed to work with the prepunched chassis sold at AX84 but will also work with a Hammond 16 x 8 x 2 chassis. The dimensions are 16.25 x 2.5" to work with the AX84 head cab. Send the Corel file to BnP Lasers to get the plates made. Any changes, such as changing fonts, will have to be handled by BnP. The Adobi file is just there so you can see what the plate looks like. More will be added later. Save the Naked Amps
