Thank you .. I got a reply immediately..!
“If you remove R49 and short R48 this should bring the output level down to where you want it.”
July 17, 2020 at 1:54 pm in reply to: Is it safe to short the ring to ground by using a TS plug in the EXP jack? #126277zmixMemberI received a reply from John Pisani, the chief engineer for New Sensor / EHX.
He said that using a TS plug in the EXP jack is no problem at all, and explained that the power to the ring connection is via a 2.2k resistor driving a 5V Zener to ground, and shorting across that Zener (by inserting a TS plug) will only amount to ~4ma through the resistor.
Great..!
For my own clarification, I crunched the numbers:
9V supply, 2.2kΩ to ground = 4.0909 mA through the resistor
9V supply, 4.0909 mA through the resistor = 36.818 mW dissipation
The 2.2kΩ resistor will only dissipate 1/27th of a Watt, so there is no danger of that 2.2kΩ resistor overheating.
Therefore: Using a TS plug in the EXP jack is safe.

I’ll post any information here.

September 25, 2018 at 3:05 pm in reply to: How about a chart of *Maximum* DC voltage allowed for each EHX pedal? #124343zmixMemberClearly that warning is necessary and obvious, bot does not address the topic.
For example, the DMM actually specifies a maximum voltage of 10.5Vdc , which is the sort of detail I’m asking about here.
zmixMemberQuote:Hello folks,i really loved my Memory Toy, as it was a big part of my Sound in Modern Jazz Music. I really liked the Modulation, which gave slightly detuned movement to every note. Sadly, my toy broke. After much consideration, I now bought a Memory Boy, as I thought it could do exactly what the Toy did, but even more.
But now i find myself having a hard time to reproduce the “movement” of the “Mod”-Mode of the Memory Toy on my new Memory Boy.
For my ears, both “Vibrato” and “Chorus” have different charachteristics then the “Mod”-Mode of the Toy.What does the Modulation of the Toy really do and how can I tweek my Boy to sound like the Toy in “Modulation”?
Thank you guys!
I have the Memory Toy and the Deluxe Memory Man TT and I have no problems duplicating the modulation effect of the Memory Toy on the Memory Man, it’s a slow triangle wave modulation,
On the Memory Boy, set the toggle switch for the LFO shape in the up (triangle) position and the LFO rate switch in the down (“chorus” ) position then set the “Depth” knob to about 10:00.. this should be close to the Memory Toy.zmixMemberQuote:Quote:Thanks for the speedy reply! Any luck with the actual milliamp requirement?Nope
Resurrecting this thread..
I just made some measurements of 3 of my modern Electro Harmonix pedals when driven by a regulated, low impedance power source:
Deluxe Memory Man TT-1100 typical current draw: 160mA, though at minimum delay time I measured 190mA and at maximum delay time with all LEDs off (and pedal bypassed) I measured 140mA
Ravish Sitar (rev “F” PC board, metal washers on the jacks)actual current draw: 150mA consistently
Memory Toy actual current draw: 18.5mA at maximum delay time and 23.2mA at minimum delay time.
The analog delay units draw more current at shorter delay times due to the higher clock frequency.
