classic pre partner for Quad 405?

Thanks for that - if I've understood correctly then changing the voltage x3 (ie. 0.5 to 1.5V) does indeed give a shift of between 9.5 and 10 dB

the other thing I had come across on the dada site was this passage relating to resistor values for 405 gain reduction:

It's stuff like this that makes me hesitant to simply buy a kit of parts on ebay. Does it also vary from one set of boards to another?

 

The cap does need changing along with the resistors in order to maintain the low high pass filter characteristic.

Same for all boards.

PS: PM sent.

 

realise the quote is slightly odd out of context, the question which prompted it was:

from: dada forum here

 

Been working through various sources over the past week and the drop to 1.5v does seem to have been the right choice.

LDR passive now slotted back in and depending on medium and time of day am generally between 1 & 12 of 24 steps so still plenty of scope to go louder.

Many thanks for your time Rob.

 

Glad it works well Robert, and good to meet you.
