Bluebird Tweed 5e3 £450

Bluebird 5e3 Tweed 
I’ve had 3 5e3s now and each one slightly different. 
This one is made by BlueBird Amps in Staffordshire. 
It has a few mods , I’m not sure what they do but one is a MV 
there is a 3 way mini toggle and a 2 way . 
Also an ext speaker out . 
Lovely little Amp and any trial welcome 
based in Stourbridge. 
Post / meet possible also 
please see pics for better info and I’ll try to answer any questions.

The three-way is probably a negative feedback switch. Adding -ve feedback allows more headroom but seems quieter. This is a really common way to mod the 5e3 circuit. 

The other may be a fixed/cathode bias switch. 

There are lots of things they could be, but Rob Robinette lays out the tweaks and mods you can apply to the 5e3 circuit here;
