Hopefully people are still here
I'm working on building a pair of MKIVs, however between the Poseidon board and the Classic Valve Cap board, I'm a bit confused. This is the Cap board and schematic:
These are the two transformers from DynaKitParts:
...and this is what I have so far:
So some questions regarding the cap board:
1. Would the "rectifier output" connection be pin 8 on the 5AR4?
2. Assuming "power ground output" means the black wire on the A-470? ... would this also be run to the negative speaker terminal?
3. For Transformer Bias Tap, would that be Red/Black on the PA-135?
4. For Transformer Center tap, would that be red/yellow on the PA-135?
5. Where do eyelet #6 and #8 correspond on the Poseiden?
Sorry for all the rudimentary questions. While I can make assumptions, I want to ensure everything is exactly correct and consulting the experts is always important! :)
