Wow, I just checked the price of the Allied 750VCT transformer and it's $61 cheaper than the Hammond 374BX at AES. I knew they were cheaper but didn't realize it was that much cheaper. That's a nice set of output tubes difference. I know George likes Allied power transformers, I may have to think about this again before ordering my 374BX.

If you decide to go the Allied route, don't forget to grab your Triad C-14X choke from them too.

If you are in Greece, your mains voltage will be 220-230volts, so I don't think that cheap Allied transformer would work as I think it only has primaries for 110-120 volts.

Yeah, tough decision. I decided wisely to splurge on really nice outputs so saving some money on the power side would be nice. My original plan was all Hammond for power and choke.

374BX & 193J Choke from AES: $142.00
6K7VG & C-14X Choke from Allied: $62.00

That's a significant price difference. Not sure what to do.

Yeah, jimazz is going to have to go with a Hammond with universal primary. 374BX is the best bet for him.

For interest, I am using the Hammond 193H 5H 200mA choke and have zero hum on my 92dB speakers.

Sounds fine to me. Almost exactly what I am doing. It will work fine with 6L6GC and EL34's as well. In fact, I'd drop in a set of cheap Chinese 6L6GC's when you first turn it on to make sure everything is working "just in case".

TOTAL (with shipping - found them in Germany)) about 440euro ... quite much ... (shipping is 45 euro)

as George told me the hammonds are good but he prefers edcor better, so no hammonds for me

three options left

1. Edcor CXSE25-8-5K

2. Transcendar 5k- 8 ohm 10W wit UL tap

3. Transcendar 5k- 8 ohm 15W with UL tap with taps for both 4 ohm and 8 ohm

edcor or transcendar ??

btw, the pcb's arrived yesterday (ty George) and the stuff from digikey .....
