iv had two rare parts kit now
well packaged as described good delivery time
very sound trader.

I have as well bought two of these rare parts kits some time back but forgot to post the positive reply.. Sorry about that, (for some reason my account went away).
Just have to say THANKS! great product, and fast shipping! (may be ordering again soon, I just love putting these boxes together).

I must say it is a pleasure to do business. I have also purchased two kits and am totally satisfied. super fast shipping Thank You



Just bought two more.

I just put in more options for the 'Rare' Parts Kits. They have all new components the only differences are the 2SC1583's and the 2SC2291's are used in Options 1B, 2B, 3 and 4. There is nothing wrong with used components as long as they are tested and work correctly and within specification.

I have torture tested some (including soldering and unsoldering them 5 times), then run them for a month to make sure that they are like new, and to be honest, there is no difference, between the new and used ones except the leads are a bit shorter.

Notes:

The differences between the five options below which all work as well, and have been tested on the forums (you only need one option for each x0xb0x):

Option 1A and Option 1B: The same transistors as an original TB303 Bassline. The only difference is that 1B has a used and tested 2SC2291 and 2SC1583's.

Option 2A and Option 2B: The same transistors as a later model TB303 Bassline. The only difference is that 2B has a used and tested 2SC2291 and 2SC1583's.

Option 3: The same transistors as the original x0xb0x. With a used and tested 2SC2291 and 2SC1583's.

Option 4: A mixture of the same transistors as the later model TB303 Bassline and the original x0xb0x. With a used and tested 2SC2291 and 2SC1583's.

Got my kit today, thank you. Business was a pleasure.

Please see the first post.

I need to clear up an issue with the used 2SC1583's and used 2SC2291's, as I was asked a couple of times and assume that I was no clear:

All of the used 2SC1583's and 2SC2291's I send are tested.

I randomly selected and torture tested some of the used 2SC1583's and 2SC2291's to ensure that the used ones were robust.

BUT, you will not get a torture tested one, only a fully tested one.

I initially tested some like this to ensure that they performed exactly the same as the new ones when soldered into a circuit, and they do.

To test all of them:

1. I first check that they function properly, i.e, that they are not faulty, with a proper transistor tester.

2.I then check the Hfe, to make sure they are withing specification as stated on the datasheets.

3. I then test them in an actual circuit. For example every 2SC1583 is tested in a standalone TB303 VCO, that I constructed for the purpose.

I can therefore easily substitute a new 2SC1583 for example, and compare the waveforms, which are identical.

4. I can therefore state that there is absolutely no difference between the used ones and the new ones, once they are in a circuit.

Therefore, if a x0xb0x was construced with used ones, you would not be able to tell!

Got my (Option 2) kit today - pleasure doing business! Great communication, and prompt delivery (from 1/2 way around the world) - thanks!

Thanks. The parts came in the post today.

I have just added another Option, there are Six now, so you can get different combinations of the transistors.

I made Six options as these are what people have asked me for. That way people can see how much the various options are.

I have added more 2SC945's in particular as some like the sound these make, as they were used in the later TB303's anyway.
These are the real NEC ones, and not the fakes floating around.

Notes:

There are only a few real differences in the Options:

* You only need 24 NPN Transistors: - Either 2SC536(F)'s OR 2SC945(P)'s
i.e., 2SC536(F) x 24 OR 2SC945(P) x 24 for a x0xb0x.
(They both go in the same way around, so the instructions are the same for both).

* You only need 10 PNP Transistors: - Either 2SA733(AP)'s OR 2SA733(P)'s
i.e., 2SA733(AP) x 10 OR 2SA733(P) x 10 for a x0xb0x.
(They also both go in the same way around, so the instructions are the same for both).

* You only need 1 x 2SC2291 + 3 x 2SC1583's - Either New OR Used
Both work as well as each other and go in the same way.
The used 2SC2291 and 2SC1583's are what I am using in my x0xen!

* All of the other parts are the same!

got my kit today, well packaged and fast shipping thanks again !

[slow_riot]

ACK!
be careful with chips/electronics so close to the magnet in the turntable platter!
yikes!

I recived these chips today. very high quality service.

I had them near a crt monitor at work for a little while (maybe 1 & 1/2h hours total) between 1 1/2 and 2 1/2 feet away before realsing that that was maybe risky.

will i have done any damage does anyone know?

cheers.
