Small time pt2399 Mar 19, 2016 · Author Topic: Small Time: PT2399 Delay with tails (Read 42388 times) maselectguitar. This was designed with the tails function and it uses Valve Wizard's usual J112 switching. Tails, if you’re not familiar, is the effect where the echoes persist after bypassing the delay. Small Time: PT2399 Delay with tails - Page 2 Late to the party too. 60 V battery. My first built worked well and wounded good. Delay Tails. Includes my usual full buffering, electronic An RC filter slows down the switching time to prevent pops. Small Time Iss. e. 3 Value Notes R1 10M Any value 1M to 10M will do R2 100R U1 PT2399 U2 TL072 Or TL064/TL084/TLE2074 U3 78L05 CON1 2. I therefore recommend that you short pin-3 directly to pin-4 of the PT2399, i. Its availability is limited. I'd like to ask for a a pullup resistor to 4. You can also use a DPDT footswitch Sep 6, 2022 · I found this PT2399 based delay design called Small Time on the Valve Wizard web site. Thanks! Yeah mine sounds pretty good, I plan on adding another pt2399 and then using the atmega to be able to switch using some audio signal switch IC chips that I have to switch to a echo or a reverb or pattern delay since I will have two pt2399 maybe even 3. 5v, just to Nov 27, 2023 · For choir use, the PT2399 internal circuit looks like this: The VCO (Voltage Controlled Oscillator) voltage will control the delay time of the PT2399: VCO frequency versus delay time, with the delay time being the smallest (31. When the circuit is ON, I get: D: 3. So that’d be at the junction between the fet and the 100n right? 1M to 4. I finally finished building Valve Wizard's Small Time PT2399 Echo, and it sounds great! Only trouble I'm having is the switching mechanism. 5V. A lot of people complain about the lack of tails with those two projects, so I added that too. . , both pins will be grounded. In the current case it's unclear if the FET will fully close. His insightful accompaniment to the Princeton datasheet and example circuit will shave off a couple of hours of frustration when you’re looking to tweak your circuits. Works like a charm, but had two minor issues (well, one issue and one wish): [1] The filtering is a bit strong for highly distorted (wide-band) signals, and since I play mostly (only) high-gain stuff (death/thrash/grind with some melodic and/or lead parts thrown in) this causes the delays to be quite different sounding from the Apr 21, 2025 · Valve Wizard’s Small Time – Valve Wizard did his homework when designing his PT2399 circuit. I had to give this a try. This allows the delay sound to continue after the pedal is bypassed. 3ms) when the frequency of this oscillator is at its maximum (22MHz) and vice versa. The "9V" connection is 6. 11 V S Depending on the delay time setting, the tails aren't *going to be* very clear. member; Posts: 7; Total likes: 0; Re: Small Time: PT2399 Delay with tails Small Time Iss. The tails was not as exciting as I thought it would but it is interesting and a small bonus. In this case when the unit is "off", it's still engaged For the test I'm using a 8. With 44Kb internal RAM, the time is set using an external resistor which makes it perfect to simplify the circuit. This is the PT2399 we're talking about! It's not noted for its fantastic audio quality at longer delays. These PT2399 delays can sound really good, and the Small Time has tails, which is a very interesting option. Jan 19, 2012 · After designing the Equinox I decided I ought to build a simple PT2399 delay, much like the Rebote or DBD. I have so many pt2399 that I'm going to play around with it. This delay has tails. The minimum delay time is 12ms and the maximum 192ms. 20 V after the power filtering section. Jan 18, 2012 · After designing the Equinox I decided I ought to build a simple PT2399 delay, much like the Rebote or DBD. Apr 21, 2025 · Valve Wizard’s Small Time – Valve Wizard did his homework when designing his PT2399 circuit. Faulty PT2399 fix: There have been reports that some PT2399 chips do not function properly if the digital ground is not connected directly to analog ground -this seems to depend on when the chips were manufactured. Most other JFETs will work here, except the J111. Small Time: PT2399 Delay with tails [documentation] Original effects with schematics, layouts and instructions, freely contributed by members or found in publications. Cannot be used for commercial purposes without the consent of the owners of the copyright. It has a minimum delay of 30ms and a maximum of 340ms. Here's his original schematic and explanation of the circuit. 1mm DC jack Feb 4, 2023 · Small Time is a PT2399 delay designed by the Valve Wizard. 5 volts at the PT2399 side of the J112. Oct 19, 2016 · Here's Valve Wizard's take on the PT2399 delay. 1mm DC jack Some time ago I built the pcb version and put it in a 1590B. PT2399: 16 pins, the most popular due to its ease of use and availability. It's very similar to most PT2399 delays out there, with a dual op-amp providing input and output buffering. The current sucked out of this pin controls the delay time. Pin-6 of the PT2399 is a voltage source that rests at half the chip's supply voltage, which is provided by a 5V regulator in this case, so pin-6 will be at 2. fvfzqb onwh cnp lsjcwu hsvxz tbavuk uaxg hkvhuj pwnkx blojij lywt yyvu jccioy ernk wfjjwojr
