GDS Amps 1-day 18W amplifier building seminar

April 25, 2007

GDS Amplification is holding a one-day amp building seminar at our shop in Flint Michigan on Saturday May 26. During this seminar, you will build a GDS 18W kit from start to finish. I will be there to assist and answer questions and teach you how to do it properly. You will be guaranteed to leave with a working GDS 18W amp by the end of the day. You have the option of building a full size 18W with tremolo or TMB. The cost of the course would be the same for each option but the combo kit would be a little cheaper.  Lunch and refreshments/snacks will be provided.  I may even take my espresso machine – free espresso/cappuccino/coffee all day long!

Cost for the kit would be discounted a little from the prices listed on my website. With the cost of the seminar, the overall cost would be slightly higher than just buying a kit but you would get the assistance to build it right in my shop. Transportation to and from our shop would be your responsibility. If anyone wants to come in on Friday night before, I can arrange for discounted hotel rooms and we could probably have a small get-together/greet-n-meet on Friday night.

All tools and soldering equipment would be provided with the option of buying the tools to keep. Of course you would be welcome to bring your own tools too if you wish.

I can accommodate up to 10 people max if there is enough interest. There is a nice airport here in Flint if anyone wants to fly in. We can pick you up at the airport.

The cost will be as follows, depending on which kit you wish to build:

  • 18W Combo – $950
  • 18W Head – $1000 


  • Seminar and instruction on site at GDS Amps shop for one day
  • Lunch (this is going to be good!)
  • 18W kit

  • Full assembly manual

  • Does not include cabinet or speakers 

Special deals will be available for cabinets:

  • 18W head cabinet – $200
  • 18W Combo cabinet – $300 (may be able to do better on these)

Ducati back on the road for 2007!

April 22, 2007

It has been a busy weekend.  I’ve replaced the water pump on Janice’s BMW, and now I’ve discovered it needs a power steering pump.  This wasn’t the worst automotive job I’ve had to do, but it was the worst water pump R&R.  I could do it fairly quickly now I think.  I also put the kids’ KTM 50 back together and it ran great for an hour this afternoon until the clutch disengaged from the crankshaft again.  I have a new bottom end with a fully intact crank so I guess I’ll have to put that bottom end in the little 50.  It ran great while it ran though so I think Isaac and Winston are going to have a really nice little bike to ride.

I got my Ducati all back together and I just returned from my first shake-down cruise of 2007.   It seems to run fine. I started it on the stand in the garage last week and it started up almost instantly even after sitting all winter.  It did so again this afternoon and it idled perfectly once it warmed up a little.  I am amazed at how well the Mikuni carburetors work on this engine.  I installed a 40t rear sprocket which seems like a good compromise. I installed a 43t rear sprocket last summer when I replaced the chain and it came with a 39t sprocket when I bought the bike.  It seems much less busy on the highway and still moves out pretty well compared to the 43t.  I also installed a set of gold ’99 Ducati SS wheels which look good on the bike but the paint on these wheels is pretty ugly so I’ll be painting these as soon as possible. Probably when these tires go away, I’ll paint the wheels during the tire swap and I’ll probably paint them black.  Here are a couple photos for you to see what it looks like now.

The plan now is to rebuild the original engine that came with the bike using the 944cc cylinders and pistons that I bought last fall.  I’ll install that sometime during a rainy weekend this summer and paint the frame red at the same time.   The fenders can come off in about 10 minutes so sometime in the next few weeks, I’ll yank those off, sand them down and spray some new clear laquer on them to show off that gorgeous carbon fibre.  I’m trying to make this bike look nice and run well with the smallest expenditure possible because I am really trying to save for the new 1098!

Paint for the new GDS shop!

April 16, 2007

Yesterday we painted the shop in the basement of the addition.  I may add some colour later but for now the white is nice, clean and bright.   We haven’t pulled the plastic off the desk or the lighting panel yet because we have yet to epoxy the floor.  Maybe tomorrow we’ll get to that.  The drops on each side of the workbench are airlines.  There is also an airline drop in the ceiling that isn’t in this photo.  There are doors for the shelves on the right but we removed those for painting.  We will also build a pair of doors for the storage access to the right of the lighting panel.


The J-shaped workbench is nearly finished.  It grew beyond the original scope of being a simple, 2×4 workbench.  When we finished the formica top which was the one thing I did want to be nice (flat and clean so I could see small resistors and so that those small resistors wouldn’t constantly roll off onto the floor), I realised I had lots of oak trim leftover from the trimwork we did upstairs so we trimmed out the workbench with that oak.  We had to buy one more sheet of 1/4″ oak plywood but that stuff is pretty cheap.  Now it is a gorgeous oak workbench that would almost be suitable for a boardroom as much as a basement workshop.  The next photo of the desk will be after we remove the plastic and stain the oak.
