Designing a mod

[pauldavidson1991]

quick question,

I want to build a Marshall 1959hw. The amp is 100W, but I want to reduce this can it be done with reletive ease or would this be difficult?

If it can be done with ease please explain, if not just say too difficult.

Humour me a bit and explain exactly what you want to achieve

For instance, do you want to build a 50W version with 2XEL34's (which would make it a 1987 rather than a 1959)?

Or do you want to use different power tubes altogether? Quad? Pair?

There are versions on the 18watt.com website that use a typical SuperLead front end with either an 18watt (2XEL84) or 36watt (4XEL84) but due to the nature of EL84's they do sound a bit different. Using different power tubes (and the relevant differences in power supply) will always result in an amp that sounds and feels different. In part down to the tubes behaviour, and in part due to the relevant supporting circuit/supply required for different tubes.


Be aware, that 50W really isn't much different to 100W in terms of volume, but they do behave and respond a little differently.

For many people, the best results involve a standard 1959 circuit, incorporating a PPIMV (post phase invertor master volume) AND a decent attenuator.
