Finally done: AC30/6 TB added! :)

Image

A few tests were done not only by me but even more by some fellow guitarists who didn't really understand why I was complaining about some hum etc.. "This comes with the package - it's the sixties technology! But the sound is gorgeous!"

Well then ... :D

LuciMan wrote:..... as last candidate: the AC30/4......

... which unfortunately I had to put aside because the black 30/4 panel coming from steve025uk hasn't arrived yet.

But thanks to steve025uk who supplied me with a blank L-chassis (aluminium) I could start to built up the 30/6 TB integrated Reverb (nice to use the green drill-machine, cone drill etc. again - real handmade ;)) .

This is how far I got till now:

Some minor upgrades ....

AC15: change of the 250pf on/off-switch (brilliance) to a 6-way switch (500pf - 22nF) - more variations in sound!

AC30/4: "anti-shock" socket for the EF86 with rubber grommet & TO3 insolating nippel. ;)

A few things were done...

The AC30 TB (integr.) is completed and sounds as good as the other versions.

Image

The power amp part has been changed a bit so that each EL84 gets its own resistor & capacitor.

Image

Now I'm working on the reverb part: the tagboard is almost completed - I'm waiting for the Hammond 1750A & the Accutronics Reverb Tank to complete the whole thing.

Really looking GREAT!

When do we get to hear one? :mrgreen: :jam:

One thing ends - the next starts! ;)

This is the start to a AC30 version w/o VIB/TREM quite similar to the versions Masco/JMJ, Mark/BLC & others have built: EF86, NORMAL & TOP BOOST - a version you shouldn't skip as a VOX AC30 fan. :D

Image

I'm using the standard L-chassis 30/6 holes as it is by moving the pwr-switch into the fuse hole to gain another hole for the 7th pot (cut). The fuse will be placed into the big hole which is normally used by the voltage selector (like I did on the AC15). On the top panel (which I have to design by myself) it will be the group VOLUME (EF86-NORMAL-TOP BOOST) and the group TONE (CONTOUR 6x, TREBLE, BASS & CUT).
The two valve sockets holes (one added to the existing five) on the left will be for optional reverb.

Well then .... ;)

Hi Alex,

thank you very much for your kind words!

I'm trying to work as accurate as possible - this reduces errors (I hope). ;)
Here's the status on the amp I recently started with: AC30 - EF86/NORMAL/TOPBOOST

Image

The amp is already tested & is working fine. I'll make better pics next week

Since 4 weeks I'm working together with a fellow guitarist (Karl) who does all the wood work. (he's getting the amp above) and he is half way to finish the cabinets & heads:

Image

There are two AC10 Twin cabs, two AC30 heads & one AC30 cabinet. I think he did a really good job! :D

Cabs look good but where did he get the pattern for the head baffle venting? It looks identical to the design I used on my own custom head.

I posted this on a 'venting' thread last year

Hi Jon,

We found that somewhere in the INet during research for more information - very hard to find information regarding the head. I thought this was about an original but refurbished head & I hope you don't mind that we used this as inspiration. :)
I like that pattern very much (the upper row of vents on your baffle is slightly different / a bit more to the left) - too bad one can't see it later because it will be covered.

Hi LuciMan
I have no problem with someone else using the pattern. I posted the pictures of my cab & head build as it was the 1st one I have done from scratch. My '62 AC30 was in a badly recovered '64 combo cab married up to 2 x 70w (yes TWO 70 watt) Celestion speakers, one connected to the AC30 and the other to a small transistor amp screwed inside. I suppose they thought of a way to always have a back-up amp with them at all times! I built it to give me more flexibility to just take the head for gigs as I was using it with a 4x12 with 2 imputs, one to 2 x 30w Greenbacks for the AC and the 2 old 70w Celestions for a 100w Marshall head.

With regard to the upper slots on my head baffle, you can still see them. They are lined up with the valves and the grill cloth does not have any scrim behind so you can always see your amp on a dark stage!

Although I openly admit to knowing nothing about the working electrical side of any amp I find the quality of the finished builds on your amps to be outstanding and have followed them with interest.

I look forward to seeing the completed builds in their cabs.

Regards

Jon

Hi Jon,

thank you very much for your very kind words too! :) Of course there will be more pics when the job is done! :)

The recently started AC30-version (EF86-NORML-TB) is now almost finished and sounds very good.

Image

Regarding the optional reverb part I haven't decided yet which version I'm gonna use: either the standard Fender Rev circuit or the VOX Reverb (with 3x4 switch OFF/NORMAL/EFFECTS + REV-VOL). In any case it will look like this - the components will be placed on that tagboard besides the reverb driver transformer:

Can't wait to see them completed with the amps built-in! :D

Despite the fact that the AC30/4 panel hasn't yet arrived, I started working again and completed the amp.

However, the Vib/Trem didn't work at all (no sound on that channel, only the first stage with V7 worked fine as I checked out by soldering a wire from V7/pin6 to VR2 - V8 had about 200V at the cathode) and I had been looking for quite some time including taking out both tag boards until I found the error by comparing Stephen's schematic to the original OA/O32 (see also http://vintageamps.com/plexiboard/viewtopic.php?f=2&t=104458&start=15#p1043194.

After solved the problem the amp is working fine! :D

... again a few steps further with wood work:

Image

Image

This is the reverb-version I did on the AC30 EF86-NORMAL-TB-REVERB: just a standard Fender circuit & the reverb signal path goes back into the PI (7). The upper pot is DWELL, the lower pot is REV VOL. Works quite well.
