Thanks.  It took about 3 hours start to finish and I took my time.  And I had no issues - who knew!  :biggrin: 

That's pretty darn fast if it was your first ever build! I had a hell of a time doing mine, had the 5W resistors letting out the magic smoke until I figured out it was a bad 12BH7, but I started out the gate modded lmao.

I suppose it's my second build.  I built a Headbanger in 2001 for my ER4s.

 

I was lucky - no bad parts!

Great job, bigfatpaulie. Looks great! Glad the burn-in was successful in "cleaning out" the tubes.

That's fast, considering it also looks clean! Quite the accomplishment. I think I took about eight hours building mine, but I was working very carefully (perhaps unnecessarily so), making sure the wiring was clean and every solder joint was absolutely perfect. I should probably go get checked for OCD... :p

If you engage in an endless loop of checking to make sure you have everything turned off in the house before you leave, then yes by all means get checked out :tongue:

My hats off to you sir. That is really fast. I did mine around 8 hours with a help of a friend

Fortunately, it only extends to audio-related activities (wiring, cartridge alignment, record cleaning, etc).

You're fine my friend, we all strive to do the best we can in our hobbies! ;):p

Super neat job, bigfatpaulie. I can only wish mine will turn out so nice.

While I am building my Bottlehead Crack a new avatar in tribute to its creator, Doc.

Thanks Mahdi8 and JamieMcC!  It was a blast to build.  

 

Just a warning Jamie, there are a few things that the manual doesn't tell you that threw me off.

 

On page 11, where you install the lager octal socket, you can put a lock washer between the main plate and the socket mounting bracket.  It's to balance the height with the terminal strip on the opposite screw.

 

And (and this one really needs to be fixed) on page 19 the manual has a revision in red telling you to instead of wiring  and soldering terminal 4 to terminal 22L, wire it to 14U.  DON'T solder it on terminal 14U.  I assumed I should and it was a real pain to desolder it later.

 

Finally, on the tool list they don't mention a drill, but you need a drill.  Well, you don't "need" a drill, but it's more important than helping hands and they mention those, and a drill is specifically talking about.  So, you need a drill.  I had everything preped for the build and I got to page 18 and had to stop everything to go hunt one down.  

 

A last little thing I found was that they weren't clear enough about what position is 'U' and which is 'L' (and maybe that's just me, but I had to look ahead in the manual to see what they meant).  'U' (or upper) is the spot furthest from the main plate and the 'L' (or lower) is the spot closest to the main plate.  I suppose it is fairly obvious but manual just says describes it as upper or lower holes.  It doesn't clarify if those are relative to the amp in 'service mode' or in 'regular' mode (ie, with the plate flipped, or in it's normal position).

 

Any-hoo, I had a great time building it.  I'm a little sad it didn't take longer as I really enjoyed it.  I'm glad I saved the Speedball for another day.

 

All the best!

Paul thanks, I started reading  from the start of this thread the other day and shortly after reading your post also came across a few more to do with that 14U area. Drills I have plenty of what I didn't have was a soldering iron so after a visit to the local electrical outlet today I now have a solder station and will have a practice at soldering tomorrow. I Also noticed they had a large selection of led lights which got me thinking about perhaps fitting some kind of down lighting or a pilot light after I have it up and running.

 

I am enjoying the build so far thinking through the process and exploring ideas for feet, knobs, finish etc its not often I build something for myself.

 

Making progress covering the bell end of the power transformer with a cosmetic layer of carbon fiber.

 

 

Add vacuum and heat

 

 

A little sanding and after flooding on some clear

I'd love to do this on my Mainline build that's coming up to go with a blue anodised chassis plate. Do you need special gear?

The answer is both yes and no

 

Yes, if making structural parts having the right kit is essential.

 

&

 

No, for small cosmetic parts you could try it with a food saver. Both ways will need sanding and clearing. Vinyl wrap is much easier and quicker.
