triad choke

[dgozalie]

Hello

greeting from jakarta, indonesia.. its rare for me to go get real bottlehead crack, so when someone sell it here, i grab it fast...

my next upgrade should be change it to film resistor, got a pair of mundorf 250v 100uf... got it around usd61 for pair... hope it will improve it more

now i am wondering about the triad choke.. cause i dunno the spec of the choke... here i got a reseller that selling the choke.. which one fit for bottlehead crack ?
1. Specifications:
-L: 10H @1kHz.
-IDC: 100mA RMS.
-RDC: around 158 ohm.
-Core: EI, air gapped.
-Antistatic shielded.
-Dimension: 69x48x58mm (panjang, tebal, tinggi)
-Net weight: approx. 700 gram.

2.LJ PC-10H100 choke (reactor) for power supply filter, tubes pre/amplifier applications.
Specifications:
-L: 10 henry @1kHz.
-IDC: 95mA.
-RDC: around 200 ohm.
-Core: EI, H20 grade.
-Air gap: 0-0.2mm.
-Shielded: NO.
-Body dimension: 60x47x50mm (panjang, tebal, tinggi)
-Net weight: approx. 574 gram.

please advice.. and thank you for bottlehead to create such an amazing tube amp.. love it...

I used a Triad C-7X  10 h with nice results. I placed it between terminals 13 L and 15 L. The final 270 ohm resistor in the power supply.

Those chokes are functionally not all that different.  I'd go for the one that weighs less, as I bet it would be easier to fit.
