Wtd: pre amp to suit 300B power amp with input sensitivity of 0.5VpK and input impedance of 100k OHM.
I've bought a glasshouse passive but there's no sound until I get 3/4 around the dial.

Less than £300 and compact if possible.
Thanks

What's VpK not heard of that before?

I don't know. That's from the spec sheet in the manual. It's a trafomatic 300b power amp.

I believe is stands for peak or maximum voltage

Found it, peak voltage rather than RMS. I thought it meant volts per something which didn't make sense.

That's why you need excess gain, cos of the quiet bits. I'd say a standard pre should see you through nicely.

What makes a stonker for three hundred quid I can't say, but there will be one out there!

Should the passive I have work then? There is nothing until 3 o clock then at fully open it's still pretty quiet

I'm no expert but I'm surprised at the result, what speakers are you using?

Did you hear the power amp working ok before you took it away?

Assuming the power amp is ok then this pre might not be very fashionable but is very good for the money:

Hi Steve
Is it possible to try the new pre into your prima luna ?
Bourney
19-05-2018, 05:17
Yep, I give that a go today... Just to prove the pre.

For your budget, I'd suggest a Schiit Saga (https://schiit.eu.com/preamps/Saga).

It's fine when used with my primaluna. Just some kind of obvious mismatch with the 300b.

Thank you for the kind offer though Andrew.

yes crazy that little velleman is there still . i have one modded and its been excellent . currently doing excellent service with some nice hybrid monoblocks . the words sensational have passed my lips in recent days but that might be overdoing it
Bourney

I'm using the velleman at present. It's pretty good I have to say.
