Small Tube Amp Build - Tip Series (Build Your Own Shielded Cable) 

Hi to Utah from New Zealand. My big sister lives in Colarado and I've flown over Utah a couple of times when visiting. That Utah landscape looks stunning from above I must say, cheers!

Thanks for kind comments Len. That tip sounds very logical and simple, probably why I miss d it ha ha. I tend to overcomplicate things but certainly some is always best. I will definitely use that, thanks. Just about finished designing two more amps, push pull, so good times. Cheers!

Thanks Full Wave! Really appreciate it!

Thanks PK!!

Cheers, really appreciate it!

True, however it melts like cheese and it's very stiff making it prone to breaking when worked too much. Mogami is preferable, however that too, melts very easily. Hence I make my own, cheers.

Hi, I use RS PRO Braided Wire 10 A, 1.9 x 0.6 mm, 25m rolls, made in the UK, part number 358-006. Go to RS-online dot com, and plug in the part number, cheers

Thanks John!!

Thank you!

I'm using a canon 70D camera with a shot gun Rode mic. I believe it is the lens that makes the difference in this instance however. I'm using a 60 year old prime Macro Takumar (preset version 1:1) M42, Japanese made 50mm f4. Even at f4, I rate this lens equal with the legendary Takumar 85mm f1.8, it is that good. If you ever find one, the preset version, grab it with both hands, its a gem!

elams1894 pourquoi ne pas acheter une mine de cuivre et faire soi-même sa filerie???????!!!!!!!!!!!!!

elams1894 quels avantages ???????!!!

I have some of RG174 coax cable however it doesn't suit for me. The dielectric insulator is a bit stiff and the melting point can be quite low. I just find it doesn't do what i want it to do and so I end up building my own. Cheers.

It can get a bit tricky trying to ground the shield around the tube socket. I think that the other end other wire maybe a better place, near the pot as I assume the cable will be going to the pot or input? Probably best to ground the shield at that end. Thanks for kind words, have a great day, cheers

The cable that I make ends up being just over 2mm. Cheers

Hi Sebastian. I have tried using solid core however solid core does have a tendency to snap once soldered, if you need to move the cable around. I have had it snap too many times and so now I use only stranded wire for the conductor. Cheers

@@elams1894 I'll keep that in mind, thanks a lot! Looking forward to future videos man, found great inspiration in the tube amp series!

@@sebastianvergara8175 No problem Sebastian. I have finally finished modelling the same amp with a Bass/Mid/treble tone stack. I'll have the plans drawn up in a week or two, and once the chassis turns up in the post I can begin the video build series. Its a very beasty upgrade, noticeably more gain. The 18watt push pull version isnt far away also. Cheers

​@@elams1894 Awesome! i built a similar version of the 6w marshall a couple weeks ago, thanks to a friend I managed to add a passive effects loop with a tone knob post preamp. i was wondering if it would be possible to add a separate amplification stage with only one 12au7 to create a clean channel with its own gain control (maybe reduced ratio to avoid distortion) and leave the original 12ax7 stage as the distorded one. Maybe even add some sort of switch to choose between channels. for what i´ve heard the 12au7 brings less distortion. looking forward to the new series!! cheers.

@@sebastianvergara8175 Nice work. Yes it's certainly possible to add a clean channel. I have that topography in this little amp. The crunch channel runs on three triodes (3 gain stages) and the clean channel runs on two triodes (2 gain stages). To work on two tubes, both channels share a triode. The evolution of this amp adds a 12AU7, which provides another gain stage, cathode follower tone stack, and recovery stage. However you can easily run a clean/crunch-2 channel preamp with just two tubes.

Thats the way, I do the same, good stuff!

As I alluded to in the vid, the insulation melts veryveasily on most bought cable, esp Mogami unfortunately. Also the insulation is very thick on most too. I haven't seen any that suits what I need, hence I make my own. Cheers.
