Jonas has completed his 18W amp in both PP-18 and SL-18 forms. “The cabinet (inspired by the Marshall smallbox) was built by myself using MDF from the local shop and tolex etc mostly from Tube Amp Doctor. I also designed the logo (using the early ’60s Marshall block logo as inspiration) and ordered it from http://skyltmax.se/ (in Swedish, sorry). I am planning to make one more similar cabinet, but with black tolex.”
