How many steps are the stepped attenuators?

13

If there’s still stepped attenuators left I’m up for a pair. Just let me know how to get you details.

Yes, four available. They fit in medium size box.

Here we have Shure riaa. Was used long time ago. Since i made ear834, i have not used it. No tubes. How about $40 plus medium flat rate box. Due to heater regulator heatsinks, it does not fit small box.

Here i found very nice lm1875 kit, with jfet buffer on input, dc dervo, and in transconductance output. All including power supply on board. All you need is 2x15vac or 2x18vac and heatsink.
How about $40 plus medium flat rate box.

Have you more details ?
I can see 2 x LM1875 + 1 x NE5532 ? + LM7815/7915 + 4 x TO-92 transistors (looks to me like 2 differential inputs) but the input ceramic multi... capacitors unacceptable for 40$

If $40 is unacceptable for you, than its not for you.

 

[adason]

Besides, two jfets on the input are a buffer, nothing differential, just like b1 from mr. Nelson.

I found this metal hole punching tool, new, never used, still oily fresh 🙂
Fits medium size box. No idea of value, make offer.

Here are small mic balancing transformers. Could be used as step up for mc. $10 each, fits small box.

In the preparation for the move, i discovered these wires. I believe it says acoustic research pro oxygen free speaker cable 12 gauge.
I got two pairs. They are each ~4.5m long.
$30 for a pair, or $50 for two pairs. One pair fits in medium box, two pairs may require large flat rate box.
They are old, but look like new, just trim the ends and you got biamping covered.

Here is nice B1 buffer. Original board and original toshiba jfers directly from pass labs. Its not as professional as pass products, but it works great. Quiet and low distortion. External power supply, one input, one output. It needs large flat rate box for shipping.
To recover the board with jfets and box, make an offer. I do not use it anymore since i use mostly active crossovers, and they serve as master volume.

Interested.

JLH well working, well build 10watts classA amp. Powered by external linear regulated 22 volts dc supply. Nice case, enough heatsink, can run all day. Standard ebay boards, real parts from digikey. Asking $99 plus shiping in large flat rate box.

 

[Jeffrey 01]

Good morning. Do you have any specs on this amplifier? Like power out put per ohms per channel? Just wondering? Jeff

 

[adason]

Yes, just about 10watts per channel. I am in the middle of move, so sorry i can measure true data myself.

Btw, its a really sweet amp if you have high efficiency speakers or you use it for mid or top in biamp.
When i used it last time with mtm from two faitalpro 6fe200 and eminence horn tweeter, it was disco level, while clean an pure.
So all depends how you use it.

Most of the diy members who need to ask question after my posts, usually do not go through. So do not worry about it.

is this still avalible?

 

[adason]

Yes

 

[Cooper60hz]

Received the two boards and the amplifier in wonderful condition. Adason packaged everything very professionally shipped it extremely quick and was very helpful every step of the way. If you're interested in any of the things he has for sale I wouldn't hesitate to buy from him again.
