Baldwin to 5F6A done

[mresistor]

I finally did finish the conversion of a Baldwin Orgasonic to a Hoffman 5F6A and wanted to show you all.  Also wanted to thank all that assisted. It was really a difficult project but can be done. There is little space inside the chassis horizontally, but being 3" deep there is vertical space. The cabinet is made from recycled wood and I have no idea where I acquired the brown Naugahyde in the past but finally used it up. The cab has two spring loaded handles on the ends. It does sound somewhat like a bassman and has a little of the grind and some pretty nice cleans. The glue seemed to shrink the haugahyde some when drying so it opened up the corner seams a little.
A sincere thank you to everyone that helped.

Wow!  That turned out really nice!  THANKS for sharing the photos and info.

With respect, Tubenit

Great work

Mitred corners are a bugger, with black tolex I fill the gap with supa glue and colour with a black permanent marker pen.
you might be able to do similar with a brown marker.

Nice indeed!

[sluckey]

Very well done!

Thanks guys  . Timbo thanks for the suggestion.

All of these sweet build threads are starting to add up.
I feel a parts order coming on.
Looks great and thanks for the inspiration!

Another beauty.

That's a beautiful thing!  Very nice clean wiring and the cab looks sweet.  Well done, Sir!

Well I was playing around with bias on a set of 5881 that are not very matched, and inadvertently made contact with pins 3 and 2 on one of the sockets, like who hasn't done that? I must have bumped one of the leads. So I had to replace the 100 ohm resistors of course and while in there took some better pics so anyone interested can see the components.

I took those 5881's out and installed a more matched set of EL34's and I have to say, so far I really like them in this amp.

Very nice looking work.   

I do have a question, why did you put the turrets so close together for the yellow coupling caps? The leads are very short, I'd be worried about over heating caps soldering them in.
 

[mresistor]

Hi Willabe - the turrets are spaced exactly like the Hoffman layout. I didn't alter it at all on this one. Oh  ok  sorry   I didn't keep the heat on the wire and turret any longer than necessary to flow the solder.  I haven't had any problems in the past but in the past, and especially since I had vertical room in the chassis, I have and could have left the leads longer and then bent them underneath the caps to fit the turrets.
Good call Willabe. I will do that next time.

Doug probably spaced those turrets for Xicon caps, they are shorter in length than the yellow caps you used. (Mallory's or Mojo's?)

The yellow caps are ETR MET out of Taiwan I think..   http://www.etr.com.tw/eng/dc_use_film_capacitors/m_polyester/dc01_07.htm  ETR is an OEM supplier with major customers that include : CDE (Cornell-Dubilier), Sony, National, Canon, APC, LG, LEO, Bosch, B&D, Askey and HP.
