NOS Mullard Buying advice

[ovlov854]

M8137 is a different beast, if you are a tube roller that is. In the circuits I've tried it on (tbh not many) it has always brought heft and a surefootedness to the music. You won't lose money if it is a half way decent example, but it may cost you. Exaggerated treble is not a feature that I have experienced with them, I have with 5751 in my Vinyl1 which is a pity as it has about 500% too much gain as is.

I have had success with using GE 5751 and Sylvania 5751 in my Pre amp but the good'uns can be a trifle dear but not as bad as Mullards. They also work very well in my RWA HPA.

You might explore Brimar as I understand that many of them were made in the same factory as Mullards. I had a pair of Brimar CV in my pre with good results.

As said previously take the advice in the thread but at the end of the day it's suck it and see

Ah Joe's tube Lore- the classic!! His words inspired thousands to seek out 3 mica/ GB Sylvanias, amongst others. Prices went sky high and continue upwards; if he'd been on commission he'd undoubtedly be a multi millionaire.
