Thanks Fixxe. Now its time for mods.  ;D

The Dunlop ECB004 works fine. That's what I used and I jumped R54 for the same reasons as billstein.

 ;D It WORKS!!!!!!!!!!!
The 50K INT pot was wired wrong. I had lug one and two mixed up. Rookie move. I should say that I haven't plug it in to my amp yet but the lamp is pulsing and so is the led. I need to get to bed but thank you everyone for helping. I'll be posting more info if something else goes wrong.

That's great you got yours to work. I just wish mine was that easy to fix. :'(

Thank you pryde for the help. I'll check it tonight and see what I could find. Are you using the bulb that Bean recommends. The 7371. I have five of them and they all do the same thing.

My rate LED works but the bulb just stays on. I tried jumping the LED but nothing happens. When I move the one leg of the lamp that's suppose to go to the C of Q11/Q12 and move it to E of Q11/Q12, Both the LED and bulb work. Here's some Volt readings

Q11  C   14.9
        B   6.8/7.5
        E   7.7/9.1

Q12  C   15.0
        B   7.6/9.1
        E   7.0/8.5

Q13  C   9.5
        B   1.2
        E   0.5

Hope those readings help and thanks for the help.

I'm thinking it might have something to do with R46 and Q13. I've tried 4.7 for R46 and a MPSA18 for Q13 but seem to get the same results. I'll keep trying.
#8
Lol ;D That would be me.

Exactly. When I hook it up like it should be, The light comes on but no pulsing. I can adjust the trimmers and the light will respond to me moving the trimmers but wont pulse. When do it the other way it works.

15 on both Q11 and Q12. Both the base B and E seem to around 7 to 9 volts. The muiltemeter keeps moving. I don't get it
#11
Anybody? ???
#12
Nope. Doesn't matter. :)

Ok. I got it to work after hours of debugging. No matter what I would do/change. Nothing worked so I took the lamp out and used it like a probe. I know by doing this, I run risk of burning the lamp but I was at my wits end. I just wanted the dame thing to work. I soldered two wires to each lug of the lamp. I hooked one side up to where the lamp would go. The eyelet that goes to Q13 "C". The other wire ended up going in between R45 and Q12 "E" and it worked but this doesn't match up with the schematic. Will this be ok to do? The voltage readings looked good. I even check other univibe schematic to confirm. Any thoughts?

New to this forum. I seem to be having the same issues as Mycpotter . Everything is working except the lamp. The led is pulsing when the seed knob is turned up but not the lamp. The lamp is on and can be adjusted with the trimmers but just doesn't pulse on its own. I notice I'm the only one so far to use the 18V power supply with this project. I'm using th Dunlop ECB004US AC adapter. I'll try and post more when I get more time.
