Tempco Resistors

I had a chance to play with the 3900 ppm tempco resistors from KOA Speer. The response time is really fast. These are 5% resistors but the 25°C value was almost dead on. https://proaudiodesignforum.com/images/jpg/KOA_Speer_Tempco_1K_3900ppm_Resistor_LT1_4LT52R102J3900.jpg KOA Speer Tempco 1K 3900 pp...

Re: Texar Prism clone prototype

It could be. Its just a shift register IC driving 16 LEDs. I'm considering a spinoff of it as a VU meter or something.
Make sure it also has DC gain reduction display capability.
I still get requests for the 10/20 segment LM3914 meters we used for the Pico Compressor Gain Reduction meter.

Collective Cases +/-16V +48V "Tripolar" Triple Output Power Supply

Collective Cases +/-16V +48V "Tripolar" Triple Output Power Supply

Here's another external supply we can add to the available list. This looks to be an EljinTek at a fair price.

Re: Texar Prism clone prototype

Nice!

That I/O board in the upper right hand corner is, by itself, a useful gizmo.
The level pots are at the output of the line receiver?

The display board would also be useful.

You should consider having both as separate SKUs in your store.
I think they'd sell.
