Happy Memorial Day!!

I was watching a recent video and it was mentioned that the original designer of the Marshall 2203/2204 had passed away recently!

Looking into it, the amp was designed by (Steve) Stephen Grindrod.

He passed away this year on April 19th, 2026 at the age of 77 after a long battle with Dementia!

Rest in peace and thanks for your contribution to guitar amplifiers, and the tone on countless albums! ✌️💜🙏🙏

Whew! Been busy as hell.

New designs, initial PCBs ordered and in this week.

Gigs coming up including benefit for Taylor Animal Shelter (no kill shelter, hope to see you there).

Gotta work on the link to the website. www.rozsaamplification.com is not directing to the Facebook account!! Need to get a hold of the GoDaddy and see what's going on!

PCB costs have gone up significantly. Ordered a set of 5pc validation boards and material cost is $59.20, but shipping was $47.27, Customs/Duty/Taxes $20.73 and Sales Tax $6.39 for a total of $133.59 for $59.20 in parts!!!

Looking for additional sources. Found a new tool that pulls costs give PCB specs! Gonna try it out.

Have a good weekend all!!! :)
