Re: Marshall 1930 clone
Hi Colin
Its not my circuit design as it came from Bo Hansen. I was originally going to work to the 1930 schematic (attached). I'm not a expert by any means with regards to circuit design and upgrades but I very aware that this circuit had 2 major issues:
- it was designed at a prohibitive cost and avoided the use of a 2nd pre amp tube which I would like to incorporate as the original design was very noisy.
- the tremolo circuit was incorrect and never worked properly in the original amplifier.
I do believe that this amp was sold as a mail order beginners amplifier (e.g. Bell Musical Instruments, Surbiton, Surrey) and very few were made and sold hence the absolutely ridiculous price tag that they now sell for (£2500 upwards!!).
I can remember asking my parents back in the very early 70s for a bass guitar but even at sub £100 it was far too expensive.
Best Regards
