To improve this home made guitar amplifier, a simple resistor divider was used at the input. Power amplifier has 100W, but at 2x28VAC supply and 8 ohm speaker you can gain 40-45W and more. Transformer has a lot of stock because it is 200W. Preamplifier is powered directly from the power amplifier, through resistor that lowers voltage for stabilizer of preamplifier.
The housing is made of chipboard and wrapped in artificial leather. The speaker is not a common guitar one, but broadband from Icoon. Mask can be put. Panel was made in FrontDesigner. Then with 1:1 print was photocopied to the larger size of paper and glued on a piece of cardboard with double-sided tape.
