Thanks Tom! I hadn't checked these forums for a while and completely missed the arrival of the Torpedo III. You're not the only one with financial dilemma's now... For now, I will have to make do with the Torpedo I with a pair of Philips tubes. Oh well... But, joking aside, the Doodlebug is a...

Hey Everyone,   I just finished building my Doodlebug, and am currently enjoying a well-deserved listen to my "reference album" (and a beer :) ). The build itself I found to be quite easy, especially using the build-by-photo instructions on the diyfroums.org-site. I used a 25W soldering-iron...

I have one, and I've used it on several occasions (not on my k702 though...). Like it a lot! Especially good when working on very thick / sturdy materials. The needles that it comes with are rather thick, mind you. 

First of all the very best wishes for the New Year!   I received my Philips tubes today and have only used them for about two hours now. My Torpedo has the snubber-caps upgrade, as well as the Hammond choke, and use it for my AKG k702's. Compared to the other tubes I've used sofar (6J6, 6J6W...

Hey guys (and gals),   I'm the one who ordered the last Torpedo before Tom ran out of transformers, sorry about that...    I finished building the Torpedo last Sunday, and spent the last few days building a pupDAC as well. It was my first move into what you would call the "audiophile" world...

Good job!!  I love the green thread you used! 

Looks simple yet effective! I suppose it depends on the shape of your head whether the headband is uncomfortable or not, and whether you have hair (which I don't :) )...

I told you  I found it helpful to use a pair of small pliers to pull the needle through, you might want to try that too. 

Sorry for the slow response, I was on holiday last week... Looks like the project is coming along nicely!

I used this thin (about 1 mm) foam that is also used for packaging electronic equipment. Really don't know what the stuff is called. ..

You're welcome! As you can see in the top picture, I Ieft the most outer bumps in place as a reference for how much foam I had apply. The way I went about is as follows: remove the bumps (cut all the way around), apply the foam, glue the leather in place onto the foam  (I cut it to size after...

Thanks!   Removing the bumps is actually quite easy, they're a sort of "stickers". Once you've made a small incision where they meet the headband, they should peel right off. As for the headband itself: it's a strip of very thin plastic covered in leather. If you're going to stitch by hand, as...

I got my k702's about two months ago, and I also found the bumps on the headband getting rather painful after about an hour or so. I decided to modify the headband a little, and here's the result:        I cut off the bumps, smoothened the surface a little using coarse sandpaper and...

Hey All,   Thank you for your input, you've given me some food for thougth! Once I'll have come to a verdict, I'll keep you guys posted!   Kind regards,   Gijs

Tom, apologies! I just re-read part of the Torpedo build thread, including your most recent comments on match between the Torpedo and the k701's. I should like an amp to be able to give the k702's a nicely controlled and tight bass. The music that I listen to is rather bass-heavy and dont't want...

So far, I've done a lot of reading on both the Torpedo and the M3, and both appeal to me, but in different ways. The Torpedo comes as a complete kit, so there's no need to source parts yourself, and rolling tubes should be fun. The M3 on the other hand would make for the better learning...

I've done some more reading on the M3, and the more I read, the more interested I get... Would it be possible to build one on my plm 250/300 usd budget? And do I have to go for the S11 power source straight away as well? Or could I start off with a simpler one and get the S11 later, as an extra...

All in all, I'm thinking of spending something between usd 250 and 300.

Thanks for your suggestion!   Initially, I considered getting the Bottlehead Crack, but Doc B informed me that this amp would not be best suited for the (low impedance) k702's (at 62Ohms). He suggested the S.E.X. instead.    Also, I took a look at the Torpedo.    I've just gone...

Hey Everyone,   About two months ago, I received my AKG k702's, and have been very happy with them sofar (except for that nasty headband :) ). They're the first step in getting more into my passion for headphones. For the last 10 year I've been listening through my AKG k271's, which, for the...
