2. ODS #183 build

[Oddvar R]

Hi. I am looking for a PT that also has a possibility to run 5v relays?

If you're here in the states Heyboer makes several of them for 100 watt amps. For 50 watt amps most bigger Fender style with a rectifier circuit would work for relays.

I've been using Classictone 40-18054 for 50W builds.
Marshall laydown type, which fits in the chassis I've been using.


100/120/220/240V To 690/625VCT@150mA, 50V, 6.3VCT@5A, 5V@3A

. . . or you could run the Granger relay board off 6.3 filament voltage if you want to:

I have used these on an ODS 124 build about 4 yrs ago and they are working great.
I ran it off my 5v rectifier tap and used a Marshall 2 button foot switch with leds (its the footswitch on the Graanger site) and a simple stereo jack.
Wow I havent used the word stereo in a sentence in such a long time! Reminds when I bought my first JVC stereo amplifier in 1981, all silver, and 25 watts per side and the tuner with the long horizontal dial and the big heavy tuning knob! LOL
