PeeCeeBee Preamplifier GB

[shaan]

Well, I thought I'd turned the trimmers most of the way out, but I hadn't.😱

This time I counted, at 30 x 1/2 turns - nothing. 40 1/2 turns and I got a reading of c.70mV. I'm not sure how many turns it was after that to get to 200mV, I'd stopped counting because I was so relieved, but it wasn't many.

Offset tuned to 1mV so it's ready for testing, unfortunately I don't think I'm going to get a chance to hook it up and test for a few days now.

Thank you Shaan, once again your patience with this idiot is very much appreciated.

Hi Neal.

Glad to know it's up and running. Happy to help anytime with anything peeceebee. 🙂

Thanks for sharing this with us. Could you please share the details to order these transformers for others in India? I would like to order these for myself. TIA

Hi Hydrovac.

It seems the transformers are rated for 18V. With 500mV diode drop the rectified voltage peak will be 24.6V which is too close to the 25V rating of the main capacitor bank, a bit risky! See if you can get a 15V rated trafo.

Hi Vizeta,

The transformers are from EMD (Electro Magnetic Devices) Hyderabad.
You may contact them for details.

Oops! thanks for pointing, by mistake I posted these trafo images... they are meant for other project. I have 15-0-15 1amp transformer, which i will use on this preamp.

I have exhausted 8x10 courier bags and expecting new bundle within two days. All of the pending consignments will be shipped within next 10 days.

Thanks everyone for your patience.
Thanks.

Hi Shaan, can u tell me which capacitor for feed back and important ones in this preamp. I want to order the high quality ones.
Also please introduce which brand of the linear signature vr control for me ？
Thx

 

[shaan]

Hi CK.

There is no feedback capacitor in the preamp. Panasonic FM/M/FS are all good choices.
