REDDi parts specifications
« on: February 16, 2019, 02:18:54 PM »
What are (did) builders using (use) for REDDi power transformers?  specs? or specific available USA voltage brands?  Would my spare tube mic power supply for Sterling/Groove tubes PSM-1 work.  it powers a mic using a 5840 (6204) pentode. Im not sure of the voltage.  It already has 6.3 vdc for heater.

I have one of CJ special wound output transformers and Im about to start  the project.
I do have a 250ct @25ma, [email protected] Stancor. Its an ideal physical size for my chassis but the HV is a bit high.

I used something roughly the same.  I just dropped the volts using some RC networks.

I'm doing a remote psu module for mine  ...  signal unit 2m away   ...   then with the fine tube and CJ output traffo

A Hammond psu traffo ...  60mA of HV and 2.5A of 6.3V heater,  I think   ...  is the smallest one I have ...  used it before in my la2a build. 

It's 'over specified' and using a small SS regulator pcb   ...   so I have it able to power up another tube signal module as well.

My build is more of a CJeddi  ..  with an extra tube too  (as well)    8)
I ping therefore I am

CJ, you still making the OT for this? Is there nothing off-the-shelf?
