Mod your Beresford 7520

I guess the cutting down process should be relatively straight forward with some wire cutters etc so you can get them into the case of the 7520?

I saw this seller on ebay.
'We recommend using Black Gate (or similar) capacitors on the power rails for these opamps'.
I wonder if he means connecting pin 4 and 8 with the fore mentioned cap.

You should be on commission Trailer, just ordered a pair of 49720's for £12.49 shipped and have asked the seller to trim them down for me as he says he will do in the ad:)

I know, i ordered one. What confuses me is their advice.

*We recommend using Black Gate (or similar) capacitors on the power rails for these opamps.

Who can comment on this recommendation?

Sorry yes I meant I bought them for £12.49 each - worded that one very badly:doh:

The story so far:

I have replaced one of the THS4032's with a spare and all seems to be OK at the moment. I have not (as yet) fitted a decoupling cap - I'll see how it goes after a burn-in. Perhaps the chips are very picky and i've just fitted a good 'un.

I really do like the sound of there opamps with the K701's - They do very little wrong - Everything is there and in full control - Superb!

Well I've gone from the standard op-amps. Had the LM4562NA's in for a week or so now. Like I have said they were a big improvement over the standards.

Next step was to try out a pair of LME49720's and I've stuck them in this morning.

First impressions. The sound is a bit "leaner" and more "airier" than with the 4562's. I'll let them run in some more.

Trailer, which op-amp is for the headphone, left or right one i the picture?
