We have a limited quantity of these obsolete vactrols. This is the model which was used in DOD 440 Envelope Filter pedals, as well as DOD Phasor 595 pedals.
We were selling these vactrols made by PerkinElmer. Those recently sold out. We recently acquired some additional stock of EG&G/Vactec vactrols of the same model, which cost us significantly more than the previous batch.
Unless ordered with a kit, these ship via USPS First Class mail package.
If you are outside of the USA and Canada and want this, contact us. We'll ship parts elsewhere with a $25 minimum order!
