| − | | |
| − | * From notes on [https://www.youtube.com/watch?v=HMDGYm91Q1Y How to Make Great Looking Modular Front Panels - Part 3 Module Circuit Board Layout]
| |
| − | ** The absolute maximum of other boards I've seen is 111,5 mm and the TipTop Happy Ending Kit offers a space of 112,5 mm
| |
| − | * 114.8mm measured between 3U Synthrotek rails
| |
| − | ** 128.5mm - 114.8mm = 13.7mm both sides, 6.875mm per side
| |
| − | ** 111.5mm daughtercard, leaves 8.5mm clearances top/bottom
| |

| − | | |
| − | * From [https://www.apogeeweb.net/circuitry/TL084-op-amp.html#tl084-vs-tl074 this site]
| |
| − | ** The TL084 Op-Amp is very similar to TL074 but has high noise immunity and better offset characteristics.
| |
| − | ** The TL074 has lower noise figure, so is better for AC signals.
| |
| − | ** The TL084 has lower offset, so is better for DC signals.
| |
| − | ** The TL084 has better DC performance (low offset) and the TL074 has better noise/distortion performance.
| |
| − | ** '''You can use TL074s on the audio paths, TL084s on the control paths.'''

| |
| − | * The TL074 is $0.75 in qty 10 ([https://www.mouser.com/ProductDetail/Texas-Instruments/TL074CN?qs=AMJt07B76uv7dLYnj7iLiQ%3D%3D on Mouser])

| |
| − | * The TL072 and TL082 are both about the same price as each other, but are more expensive than the quad parts
