I am not sure how active Jef is. We must wait to see if/when he relaunches his site: http://abraxas.jefdeb.com/

The old site had lots of schematics and ideas so hopefully the new site will be equally useful.

 

An early version is sold in kit by a friend of Jef's. http://spudkit.com/

If you read through all the Hawthorne forums you'll also see modifications by Terry G to upgrade the kit.

 

Jef's builds do exceed the kit in every way. He went all out on mine, including screen regulation and the headphone adapter/output.

 

Cheers!

I think they were available in either kit or assembled for more $$.  I wonder how they get around not having filter caps in the output stage?  I was told a filter capacitance reservoir is required even though output transformers only pass AC.

Jef (Abraxas) doesn't sell kits but he does give away a lot of his ideas. His old site was renowned for it's content.

The kit version was based on the second Spud Jef designed (V2) around 2007 but is different from mine.

I don't think Jerry, who made up and sold the kits, even credits Jef for the original design anymore.

 

Jef has only built 4-5 Spuds over the years, each one a little better.

Mine is his latest (V4), built because he had some new ideas re: screen regulation and also preloaded the output transformer secondary for the phones.

He doesn't like to build the same amp twice unless someone really asks for one. 

Sorry, can't answer your technical questions, but the amp is genius on speakers or cans.

I couldn't be happier....

Is it anything similar to Bottlehead products?

post #17134 of 18741

I've only heard the Crack and the Spud is different...less lush, more spacious and detailed.

It might be similar to the BH WOT amps = Smack or SEX as they have output transformers and one tube per channel, single gain stage but the Spud uses Pentodes (SEP) and I believe the BH are triode (SET)...so different. Also not sure if any of the BH designs are tube rectified...

Thanks for the details... I bet it sounds great with those HD600s.  Maybe some day I'll get a chance to demo one of those.

I found out about Jef through Head-Fi member nurxhunter:

 

You should keep an eye on his site...Jef has great ideas and is one of the good guys!

I have that Zadie smith book but have not read it yet- the purple pink one is it any good? 

post #17143 of 18741
Haven't read it but my partner says,it is good,set in an american university(east coast),centred around a black and white american family.
It is rather a homage to E.M.Forster.
I hope you will enjoy it.

Pictured is my humble little analog set up.  Unfortunately the lighting isn't very good, sorry about that.

 

I've also got a computer set up, but it's nothing to write home about!

Got the final piece of my puzzle for a while! My E09K will go back to join the Modi at my PC.
