So you are using coils...!

I am using a jfet as primary load so I guess I should use at least 10x internal cart impedance (L=17ohm for the AT 33PTG).

This cart is similar in specs to a Denon 103R and these sing beautifully with 150r.... I will go very near that.

Thanks for the imput.

Regards

Ricardo

No, Piccolo is fet based.

Yes, very sweet through transformers, a friend has CineMag 3440's.

Piccolo seems to be only a stepup amp without riaa equalization.... Am I right ?

In that case, what where your impressions when using the 150r loading ?

Does timbre get lost ? Did you not get a wider soundstage ?

Maybe Hagerman Piccolo uses his special upper 3.18us (50kHz) corner in its transfer function built in.... this produces a boost in the high frequencies needed to cope with lathe cutting head cut off at the same freq.
If so, that explains why you need to cut high freq output by heavy loading your cart

My Piccolo has stock resistor settings, 47,100,220,470,1k,47k. PTG33 sounds fine at 100R.

Transformer loading sounds more natural, with better detail. Piccolo has a very good soundstage thou.

Not sure. Piccolo is very neutral at high frequencies, compared to transformers. If anything, transformers give better high frequency definition.

After some reading I understand my question about the upper 50khz corner can not be applied to the Piccolo. (After all it does not have riaa eq built in )

So the AT33PTG sounds ok with 100r.... did you try 220r also ?

PS: I know I am a little off topic here so this will be my last post but I really need your input.

Regards
Ricardo

I'll try it at 220 later today and get back to you.

I've been listening to music with my Piccolo set at 220R for a couple days now, and I'm really enjoying the presentation. I've got my big amp back up and running, so really don't have too much to complain about. I think I'll leave the Piccolo set at 220R for a while before going back to 47R to see if I'm missing anything.

If you are making a new wand you may try this to.
Because of the weight from the tonearm wires the pressure on the tip of the needle was not stable.

Hi, I am thinking of trying something similar, but (looking at the above photo) I have a question.

Is there a minimum distance from the stylus contact point to the vertical bearing? The above arm is very short. I would think at some point the VTA starts to vary with record imperfections (undulations) and it affects performance?

P.S my question above is a general question, not just about the arm in the photo.

Is there a minimum tonearm length, below which the angular change (when tracking warped LPs) becomes a geometric issue?
