If your business is good I can see that being the right thing for you.  I'm just really glad I was able to buy a board and chassis for my 50w plexi. It was my first amp to build and part of the fun for me was sourcing the parts and putting everything together.  I understand it might not be cost effective to spend a lot of time answering questions but that might be solved with a good build manual and refering questions to the forum.  You were great answering my questions though and I think maybe you are a person who will always give help when asked.  Anyway, if I build another amp I would probably buy the board and chassis from you again if available. If not I would probably just build my own, now that I have more experience and confidence.  Just more fun for me to source parts and I'm playing in my bedroom so have to go as cheap as possible.  But I LOVE my 50wat Plexi, it is amazing.  Thanks always regardless of what you do in the future. 

I case anyone is following this I had the indicator light wired wrong, got it working now.  Funny that I can build a tube amp but can't wire a light bulb .  Installed the LAR/MAR PPIMV also.  Man, I love this this amp!  Can't stop playing it.

I added one a couple weeks ago, turn it all the way up and sounds the same as before I installed it.  Turned down low it does affect the tone but still nice to have the option.  Turned up to about 6 and above with the volume dimed it still sounds great without knocking the walls down, still loud though.  I say go for it, easy to reverse if you don't like it.

Following layout is easy enough; would be a good idea to document startup/bias procedure somewhere, also maybe some guidelines for which wires to twist together, voltage readings, and how to discharge the caps.  I found the info easy enough on another site but just a suggestion to put it somewhere on the Ceriatone site.

Also, to my suprise, a schematic printed out as a second page when I printed the layout for my Plexi50.  Didn't actually use it yet but was glad to have it.

Amp is working now!  Had one more little hiccup; I had the output primaries switched.  I had guessed right but somehow managed to do it wrong anyway.  When I went off standby both output tubes turned into  blue sparklers.  It was kind of cool looking actually for the one second it took me to switch it off.  I switched the wires and everything works perfectly.  Has a little more hum that I would like but still acceptable.  I'll try auditioning preamp tubes, Larry grounding, cleaning up the wiring etc after I get it broken in.  Need to get a proper speaker cabinet, install LAR/MAR, etc, will be tweaking this thing for years but that's why I built it.

My problem was the indicator light.  It may be the wrong type, I'm not sure.  I've been getting parts all over the place to keep the cost down.  I found R.G. Keens tube amp debugging page and followed the instructions, PT tested out fine.  Hooked everything back up except the indicator light and voltages seem ok.  Just installed preamp tubes and they are glowing.  Still need to install output tubes and set bias but feeling much better about it now.

I appreciate the help.  I would never attempt this without resources like this.

No problem hired hand. I'm 51 so I understand.  I spend half my time wearing  magnifying glasses on my head.  I've mostly worked with DC and continuity to ground is always bad.  I know AC is different and I'm reading accross a coil of wire with taps but I still was guessing the resistance would be higher.

I haven't installed tubes yet.  Would it hurt the PT to power up with the secondaries disconnected and carefully measure the heater outputs?  If I could just get partial functionally it would be encouraging.  I'll also go through and double check all the wiring.  I have an upper end radio shack meter; wasn't real cheap but probably not the best either.  A friend of mine had one of these amps 25 years ago and I've wanted one ever since.  It was a 50 w without a master, not sure if it was JMP or JTM though.

These are one set of Magnetic components as I stated in my post.  I'm not sure where you're getting MM from, but thanks for the response.

After pulling the secondaries from the diodes I am reading about 40 ohms from each secondary to CT and about 80 accross both secondaries.  Is this normal? I read on metroamp forum that the secondaries shouldn't have a short to ground, and a short indicated a bad PT.   

As for the heaters, I noticed the sockets were reading a short to ground.  I pulled the CT from the ground and the sockets aren't showing a short anymore. The short was to the CT.  I haven't pulled the heater wires from the sockets yet. 

I did try to power up first with everything hooked up and the main fuse blew.  I'm not sure how to troubleshoot that if the secondaries shorting to ground is the normal condition. 

I am trying to verify the PT triode sold me for my marshall 50w is defective.  The heater wires show continuity to the 6.3v center tap and the 690 secondaries show continuity to their center tap.  I'm pretty sure this isn't supposed to happen but want to be sure before I buy another PT. Could someone with more experience veriy this please?  This is my first tube amp after building quite a few pedals.  Wish I had noticed before I wired it up.  I did notice before I powered up so it isn't anything I did.

I have a Ceriatone board and chassis.  I was planning to buy their transformers when I got some more money but decided to go with the Magnetic Components to save shipping.  Website said they would ship in two days.  After four days I emailed and they said would ship the next day.  After five more days I emailed again and they said had everything but the PT and would pick it up and ship it the next day, and refund the shipping. I waited a week and emailed.  Said he had been sick with the flu and would ship that day, which it did.  They refunded the shipping but shorted me 6 cliff jacks.  Emailed me again and they said they didn't charge me for the jacks.  Fine, but now I had to wait for another order, because they never mentioned it.  Now the PT, which I had to wait three weeks to ship seems to have arrived defective.  I'll probably ask for a replacement just for kicks but based on my past experience I don't even expect an answer.
