It is based on an Ampmker WF-55 kit with a few mods. The original kit is a 4w head based on the fender champ with a 6V6 output tube and a simple 12AX7 pre-amp I have basically changed the power amp to a 6550/KT88 powered design from the AX84 web site to give me 10 o 15 watt output. I added a simple tone control and master volume and changed the pre-amp tube to a 5751. this amp sounds fantastic (IMHO) its the first amp I have built and everything worked perfectly first time, a testament to the excellent instructions that Ampmaker provide. I have the Ashdown CTM15 and the cabs I have are the Ashdown VS112 and VS115. The wf sounds as good, if not better than the CTM15 and is just as loud. total cost of the build so far is around £200-£220 inc kit valve's and OT and took me a day to build. I'm guna call this amp the WF-65.5 as it has the 6550 power tube.

JapanAxe Posted February 14, 2014 Share Posted February 14, 2014 Cool! Just looking at your sig, what mods did you perform on the Epi VJ to suit it to bass? (I have one which I have heavily modded, but just for guitar). Quote Link to comment Share on other sites More sharing options...
spaners Posted February 14, 2014 Author Share Posted February 14, 2014 tried a few mods, mine is the v2 combo. I upgraded the powers supply smoothing caps, changed the coupling caps and cathode follower by-pass caps. added negative feedback , fitted a Hammond output transformer changed the valves a few times n settled on JJ EL-84 and GT 5751. replaced the stock speaker and added a switchable output selector switch. think that was about all. I took the Hammond OT out to use in the new amp and I'm going to put the OT from the kit back in the EVJ. Quote Link to comment Share on other sites More sharing options...

spaners Posted February 15, 2014 Author Share Posted February 15, 2014 Thanks 6V6, I still have a little work to do on the tone stack to make it more bass friendly Quote Link to comment Share on other sites More sharing options...
