2019 DIY valve amp workshop in Pretoria?
« on: January 21, 2019, 10:12:00 AM »
Hi All

There seems to be interest to have another workshop in Gauteng, ideally in Pretoria. We are aiming for 4 participants, but can accommodate up to 6.
Dates that comes to mind is 21 to 24 March and 1 May. Any suggestions?

If you have, or know of a venue for a three day workshop that is affordable, can you PM me please.

Hi Guys,

Im based in centurion and know pretty much zero about tube amps, other than i love my predator.
I'd definitely like to learn, keen to join if there is a spot for me, even if it is just to observe.

Built this a few years ago during a Mars workshop in Pretoria and I'm still very happy..... it has given me countless  hours of joy.  No knowledge required, ability to solder might  help.  I'll supply a basic soldering station (temperature can be adjusted) for the weekend if it will help someone to participate.

Hi Spurge

1) the workshop consist of two days of amplifier assembly. After a short talk about soldering essentials we immediately start to assemble the kit hardware. Then we start soldering the leads and adding the components to the circuit. On day 2 we complete the build, check it, and start to power it up. Once it plays satisfactorily you can go home and listen to music.
2) two consecutive days. As the planning stands now (dates may be changed to accommodate everybody attending) we'll get together on Wednesday 1 May and Thursday 2 May. You can start on Tuesday (with prior arrangement) if you are a slow worker, or if you want to proceed at a more leisurely pace. I am usually also available, before flying back to Cape Town, for emergency follow up.

Venue in Pretoria has not been finalised. Dates are 1 and 2 May tentatively. Let us know if it suits you, or not.

We build from 9 to 5 with lunch and tea breaks as needed.
3) any level can be accommodated. If you are new to soldering, we'll give you a quick course on soldering essentials. Only enthusiasm needed.
4) the 70watt stereo amplifier kit costs R11 900 (check our website for kit options, or see follow ups to this thread).
5) two day course R2400

We do workshops in Paarl too. Respond to this thread https://www.avforums.co.za/index.php/topic,77183.msg903505.html#msg903505[/size]
