Default Please check these parts for SSE?

Hi All,

I have been making a parts list for building my first ever amplifier SSE with KT88 tubes.
It will be powering my Kirishima horns (Fortex Fe206En)

Can you please help me check the parts I had to find a replacement for form the original parts list because I have no knowledge in this area?

Also please take a look at my other parts selected?

Thank you
Jock

All those parts look suitable for the SSE. You can probably get most or all of the parts to populate the board from DigiKey, saving on shipping cost.
The motor run cap is fine.
The choke is a suitable one. I assume you will mount it under the chassis as
it doesn't have the bell caps to give a nice finished look.

The transformers you've chosen are exactly the same as what I have in my SSE. I can tell you that these will give you great performance.
For a bit more money you can also get an Edcor choke, this choke is what I have in my SSE

This is also a suitable one for less money -

Good luck with your build.

Thank you Spendorite for taking the time to check these parts out.

Now this part is covered I going to look into the volume control, switches, tubes and the power 'thing' with fuse and tube sockets,

I am sure I'll be back here once more before placing the final orders

Almost ready to order the parts.
A questions about the chokes

From the chokes below, trying to decide which one:
Which one would be most suitable and why? (don't know what the specs mean)
Are there any differences to be expected in sound quality?


Triad C-14X - 6H, 200 mA, 150 ohms

https://www.edcorusa.com/cxc100-7h-150ma

Thank you

One difference is DC resistance, one is 75, one is around 100 and you say the Triad is 150.

If you run PSUD, you'll get different B+ voltages depending on what inductor you use, but it also depends on the power tx and the value caps.

But in general the more resistance the lower the voltage.

I can't say if there would be any sound quality difference. Any difference would probably quite small.
I got the Edcor cxc125-10h-200ma. Here is my reasoning...

I got all my transformers including choke from Edcor in one shipment. The total shipping cost to
Toronto, Canada was $126.00. The difference in cost between
the cxc125-10h-200ma and cxc100-7h-150ma is just $15.00 and the smaller choke
would have resulted in only $3.00 less total shipping cost so for me it was a no brainer to
chose the cxc125-10h-200ma.
My transformers along with this choke gives me great performance from my SSE.

Look at Sprague orange drop for coupling caps...716p series if you can find them..but both are very nice caps...and not boutique pricing.

Thanks for all your input!

I found out that this part (resistor 10kOhms 3 W) is out of stock at mouser
283-10K-RC Xicon | Mouser

Can this be used as a replacement?
ERG-3SJ103V Panasonic | Mouser

I notice that there's a difference in temperature coefficient 350 vs 300 PPM / C and the operating temperature range -55 to +235C vs -55 to +70 but do not know if this is relevant for use in the SSE.

Thanks again
Jock

Hi Jock,

This is looks like a better alternative:
ROX3SJ10K TE Connectivity / Neohm | Mouser

Thanks,
Bibin

Thanks Binbin,
You're right, the specs match exactly. Unfortunately minimum order on that one is 1000...
Best regards,
Jock
