Here you can find the listing of the used components.
I have bought the transformers I used from a eBay store, which exists no longer, but there are a lot of replacement transformers for AC30 available.
The power transformer should have the following specs on the secondary side:
275V – 0 – 275V @ 200mA sec1
0 – 3.1 or 0-6,3V sec2 @ 4,5 to 5,5 A (depending on the quantity of preamp tubes)
0 – 5V @ 2,0 A (for GZ34 tube rectifier)
There are many output transformers available for AC30.
I used “Mallory 150” for coupling capacitors. I have been told that “Orange Drops” are not the best choice in AC30, but i haven’t tried that out. I used carbon compositum resistor for anode and kathode resitors, otherwise I used metal film resistors. The metal film resistors I used are rated for 1 Watt, but as you can see with the carbon compositum resistors, 0.5 Watt should be sufficient.
