Title: New Amp Build Project
Post by: Dmoney on October 08, 2011, 12:51:59 AM
No photos yet...
I'm picking up an old amp with a similar layout to a super lead.
2 input, 8 controls on the front. the chassis is drilled for a 100watt setup but only populated for 50watts.
space for 4 power valves, and 4 preamp valves already. layout is very similar to the superlead with the HV caps between the power and output transformers.

I want to work on this on and off and try a few things out in it. I'll probably build another high gain of sorts.

There are some bits id like to try, like a filtered IEC socket (just to see if it makes a difference). I'd also like to beef the power up to 100watts and try split bias. maybe mix 6550 and EL34 output valves. Maybe use a cathodyne PI a la VHT.

could do a really slow build dairy?

I've been thinking about learning how to build amps, so it would be great to see a diary to give me that extra drive :)

yeah just whack up a wordpress blog and get some good photos in there.

Im also interested about the filtered IEC's its something i've never tried but have thought about.

I actually may do it on my next build

i might do that first. so i can get a good A/B comparison. best chance to see what difference it makes.
I want to reverse engineer the DC heaters in my Avenger too. maybe.

should get the amp (or amps) today.
2x Laney 50watt AOR protubes.

I just wondered, I know where you can probably get all the pots and wires for an amp. But what do you actually do when it comes to the circuit boards, etc?

well if you had all the stuff you could design and etch your own. I've etched boards when i was in high school, but nothing complex.
Or, you can buy various board materials and use eyelets or turrets to wire parts point to point. obviously you can mix and match. just depends on what your trying to build.

A great company to deal with if you want no response to your emails!

I have good experiences with them. Never mailed them though.

Actually I used their extended Lightning board for my first self built amp. Then I found out that it did not line up well with the tube sockets in the chassis. I then changed the board to one where I layouted the turret positions myself. The turretboard board now lives in another amp.

Your amp looks very clean.

Cheers Stephan

Yeah i have been waiting for about 3 months to replies to various emails.

Theres no way im phoning them as it would cost a fortune and i'm definitely not going to buy something if they cant answer my emails i wont be confident that they will  ship my order either.
