Good point about the headshell mass George.
Newer Terminators have 3 SS grub screws to pop in to mass it up for lower compliance carts.

On the trad arm I needed to go from ~8g Technics headshell on the AT 33 PTG to 14g (Sumiko + 3g) for the Spu with suitable extra counter weight.

That gives me some reference point I guess. I could make the SPU Royal N spacer (need for using trad non SPU headshells) out of Brass - ah hold on I have some gunmetal in the workshop from help a chap out cutting a gunmetal armboard for his SP-10 - that would be perfect. If that is too much I could always make some gunmetal grubs ala Terminator.

Not had any pressure probs. The pump is pretty hearty. I use a 5l smoothing tank (petrol can) - the silencer idea is interesting. Can't say the very slick hiss annoys me though.

Hi Speedysteve7

What is the load you are using with the AT 33 PTG.

I plan to buy one but can not get any info about load.

Regards

Ricardo

I was using 1.8g. From memory the range is 1.6 - 2.0g with recommended 1.8g. Someone on Art of sound like 1.85g so around there anyway.

Thank you.... I will try that VTF.

But do you know the resistive load of the cart in the phono preamp ?

Regards

I used a Dynavector P75 and some use it on the Direct Current or Phono amp setting which is 0.
I found I liked it best on 30 or 40ohms - so pretty low settings work well with this cart.

I have a feeling the P75 went, 0, 30, 100, 470 or something similar.
I have found in playing around with this the higher the set resistance the more treble / slightly less bass you get.

I like mine loaded at 47 ohms the best. I've tried 100 and 150.

Thank you so much..... It seems there a consensus regarding loading this cart with low r values. This should reduce high freq response....Should it mean that the cart sounds "light" regarding other carts ?


What type of phono preamp are you using Jeff ?

I believe loading the PTG down helps tame the raising treble slightly. So yes, it could sound a little "light" in some systems.

I'm using a Hagerman Piccolo for step-up into a Pass Pearl.
