First off, great job. I can tell it sounds excellent and await another clip. VHT Deliverance uses a parallel triode for the first stage, are you liking that a lot? Did you have to change much else to compensate for the difference in impedance?
Second, how did you get the light on the front to blink like that? That's actually kinda cool.
There you go.
Save? This doesn't exist anywhere outside my flat, unless someone else has built one. I know some people have 6V6 Plexi's and 800.
xicon caps, metal film resistors, F&T filters. I decided not to use Orange Drops to save on the costs bit.
I decided to save some cash and use a combo of what I had lying around, plus some new parts.
Clarostat pots I had kicking about.
External Bias
Silicon wire (kind of looks weird to me)
4ohm tap is wired directly to the DC blocking cap in the negative feedback loop. I never use a 4ohm cab, so I added hard wired 16 and 8 ohm outputs. (1x16 and 2x Parallel 8's)
I didn't do much to add the parallel triode. I just added the same value cathode and anode resistors in parallel to the orginal values. Making the total resistance at those points exactly half the original value.
I'm sure I could do more by splitting the cathodes and biasing the two triodes differently. I've never tried that. The main benefit I was hoping for was the 3dB noise reduction I believe you get.
The standby cuts the HT right after the secondary and before the rectifier.
The pilot light flickers at 50hz (mains frequency) since it is a 240v AC lamp. not a 6.3v pilot powered from the heaters.
In person, the light doesn't really appear to flicker like that. It looks worse on youtube because the refresh/frame rate of my macbook camera must be close to 50hz or something similar. It's a standard kind of video 'distortion' you get.
