Title: TS TANTALIUM CAPS
Post by: Ricardo Antunes on December 07, 2004, 05:30:07 AM
Hy friends!!!
About the two tantalium capacitors in the TS circuit, can they be changed to a poly film, ceramic, electrolitic or what?

Thanks  :D

I would go with polyester/Metal film for those values,  then install as "non polar"  either way around.

For better sound clarity I would choose any type of film cap, especially high ESL film caps like inexpensive Xicon "greenies".

It is always funny to me that clarity is important in distortion circuits. :D

It may be that the ultimate TS sound has as a component, the non-linear distortion of the tantalums. :shock:

I gave up looking for 9V mojo in Ceramic Caps and Tants a while back. If it's there, you canhave it !!!
 They sure work good when that is what you have. Hard really to tell a different in just one cap type, linked in a chain IME, most of the time.
 Someone suggested you can't find the difference if you 'hide them in Picofarads'. Across Q2 B/C junction in a FF though, Mica 'beat' ceramic...I just go figure it's all application and tend to stay away from liberal use of ceramics.

I been saying that for years about the TS and tants.

 How many of you here have heard a REAL 808 that has the sound???

Thats why I when I see people saying they got the TS clone just like the real 808 I don't believe it.   I have been unable to find a tant that has the sound of  a few of the 808s I have heard.  I have found a cap that is close but not 100%.  The tants in the 808s that sounded good had no markings but the .22uf

If there is a difference (and there could well be, depending on the circuit), remember that a particular type of cap might be "good" (in an a FX sense) because it is "bad" (in an electronic engineerign 'ideal capacitor' sense).
Where I have found tants necessary, is in circuits that need high capacitance (100mF) and very low leakage. (this wasn't a tone problem though).
