Yes a lot of Nik's amps have the post phase inverter master volume. If you don't want too much volume you might want to go with the 18 watt Marshall clone. But remember, with a master volume you can go with a higher wattage amp if you want that distorted sound. Frankly, I prefer to use pedals because if you want that clear sound when you turn your guitar's volume down you'll get it. The post phase inverter mod is the only way to go because it keeps the basic tone of the amp intact whereas, many amps that are on the market don't do this and it is next to impossible when the gain is up to get a clear sound. If you want the Marshall sound, go with the Marshall clones. If you like the Fender sound, go with the Fender clones and for the hybrid go with the Trainwreck, Matchless and Ceriatone Overdrive.

It would seem to me that you are taking out a couple of the "plates" which control the electron flow. Less electrons=less power.

I've got a soundclip that I want to post for the Tweed twin that I just built. Could someone give me the "how to". The clip has a lead with the Tweed twin and rhythm on the Ceriatone Plexi50. Thanks

How do I post a soundclip for the 5E8A tweed twin? Thanks

The amp sounds very good right now. Even on the Sozo website there is some ambiguity. Maybe I'll reverse them. Then again...

I would go with either the Weber British series ceramic Silver Bell or the Scumback M75 both come in higher wattage versions. Because you are pumping quite a few watts into one speaker you should be able to get it to break up somewhat like a greenback. However, the bottom end should be cleaner than with a greenback.

I recently built the Plexi50 lead and installed Sozo vintage caps. There is an orientation regarding the direction of the caps as regards the black band. I installed them with the black band facing the plate current side and not the tone circuit side. I have read recently that this is incorrect. Anyone done the same thing?

If your going to run your Plexi at high volume you're going to need a high wattage speaker perhaps 100 watts. I know that Weber makes British styled speakers that run upwards of 100 watts as does Eminence. Celestion has higher wattage speakers that might work fine. Most of the speaker websites have soundclips so you can listen to prospective choices. I would probably go through a Weber V30 type that is rated for high wattage. You may have to go on the Weber website because even though SpeakerTone.com stocks Weber's they only have one British toned speaker that is rated at 100 watts the Alnico Blue Dog. They have plenty of 50 watters if you are playing lower volume with a distortion unit.

On the cord itself it has the proper names for each terminal, after I scrutinized the friggin' thing!

I set them at 32ma, sounds great!

I just built the Plexi50 and it is GREAT! I used to play professionally during the early 70's to the mid '80's and believe it or not I never owned a Marshall! But I've had a lot of other amps. Mainly it was Bassman's that I used including three '59's, two blonds, and one blackface. The amp that I had from nearly the very beginning-1967-was a Vox AC100 built in 1963. I also had two HiWatt 103 100 watts-1 stack w/head and 1 head circa 1970 that I used until the last performance in 1985 that I did. A matter of fact that last gig was done with the Vox AC100 (w/master volume for a dirty sound) and the HiWatt for a clean sound. Now my question is what Ceriatone amp do I use to complement the Plexi50, either run together or separately with an a/b/c box? I've been leaning towards the Tweed Twin, the HeyWhat 504, the Bassman 5f6a w/4x10's, or the 36 watt ef86. What's your thoughts on this? I want a complementary sound in other words, different than the Plexi but not so different as to not sound good together.

Thanks, hiredhand I found a couple of minor problems before I fired the amp up and now it seems to be idling quite nicely and seems very low noise. I've got to hand it to Nik, he does an excellent job with his kits and completed amps. I'll post my review once I break in all the capacitors/etc.

What kind of milliamps are you guys running in your plexi50? I was thinking of 25-30.

I just built the Plexi50 lead unit and are getting ready to fire it up (once the tubes arrive) and was wondering if the negative/ground center pole on the Bulgin receptacle should be facing up or down. I have seen it both ways. In other words the hot and the return would be reversed if the ground pole is facing up. On the Ceriatone website I have seen it both ways but on my Apple computer it (ground) is facing down.
