Haible Son of Storm Tide Flanger (SOST)

Haible Son of Storm Tide Flanger 2015

SOST Demos

Demo by Lars

Amazing demo by the bad producer (original SOST board)

Flanger is a bit of an understatement for Jürgen Haible's incredible reinvention of a vintage effect unit. The Son of Storm Tide Flanger is now back in a slightly modernized version:

  • PCB size has been reduced to 6" x 4".
  • Obsolete CA3046 has been replaced by LM3046 (on the bottom side!)
  • No more upright resistors or resistor arrays
  • 1uF Film caps as an alternative to electrolytics
  • BF545A (SMT) as an alternative to BF245A.
  • You still need 2x TDA1022 BBD chips as well as 2 AA 143 germanium diodes (see rare part kits below)
  • MTA-156 power connector for +/-15V (or experimental: +/-12V) - don't install the onboard-PSU parts if you use a regulated power supply!!!
  • Some connectors have been moved to the edge of the board to allow connecting component pcbs via pin headers - downside: space may be too tight to use normal headers. Workaround: use (breakable) precision sockets for manual wiring or testing.
  • Board is big, very dense, requires some rare parts (see rare parts kit below) and may have to be hard-wired due to space restrictions - wiring can be a challenge. Only recommended for experienced builders!

Configurations

The SOST pcb is available in different configurations:

  1. Bare pcb - requires hand-soldering of LM3046 and bypass caps in SMT - no components soldered in or contained!
  2. SMT version - LM3046 and bypass caps in SMT reflow soldered in.

While stock lasts, there is the option to order the following not-so-easy-to-find parts along with the SOST ("rare parts"):

  • 2x TDA1022 BBD ICs (New old stock)*
  • 2x germanium diodes AA 143

Please note: the TDA1022 are obsolete for many years and I don't have the time and means to test these chips - I cannot give any guarantees that they actually work. However, I obtained them from a trustworthy source who bought them decades ago when they went out of production - so far I haven't had any reported as bad, but that may not mean anything. So any purchase of TDA1022 is at your own risk - I can only pass on what I bought to make this run possible. If you do not agree to this, please don't order the rare parts kit.

Order Info / Disclaimer

A limited number of pcbs is now available for experienced builders. Please not that this is a DIY project involving a fairly complex board designed to be powered by +/-15V (+/-12V seems to work as well but may need some adjustments).
