Pacific dac: Lampizator's new top of the line dac

[wisnon]

The internal ballast resistors are only 5 watts
The relays used are rated at 2 amps.

5v is the max heater voltage used. 45 is the lowest 2.5v iirc, and 300b is highest at 5v. Total wattage of tubes allowed is about 8w or so.

Good to know now that I have a PAC.

The new gg2 uses diodes I’m not sure as to what tubes are ok. It’s more then just tube heaters at play here. The diodes are used to isolate the plate to ground voltage potential. the pac is not the same it used the little tube not as a diode but more like regulator. in any event I like to get a blessing from norm as he talks to yoda.

My PAC has a PX25 setting.

that is the label...not the exact spec. Mine does not say px25 or T100. Those are added as they are within tolerance of 101d and 390b setting and people want to use those tubes.

for GG2 I would stick with the label until confirmed by Yoda. We only discussed Pac...though I suspect the same applies to GG2 as well. Most important is to make sure you insert tubes AFTER verifying what position is selected. 300b setting on a 45 tube could be detrimental.

Just curious to know what it supplies with a PX25 / RD in it Norman. I am surprised no one has posted the answer given how easy it is to do.

Given virtually no one uses NOS PX25 1.8A would be a good answer since that is the KR spec.

I’m using original PX25 to good effect.

Well then there should be no problems with AD1n or RD27AS if you are using a Pac.

All this doesn't really make any sense. Confused? You bet.

Justin...I use Tesla ad1n and KR px25 regularly in a pac no issue. Also have the philips 4683.

Your PCM is DE 532? What’s that? Mine says DS57

Maybe Digital Engine 53mk2. As Pacs had initially Digital Engine 57....but I might be very wrong..

Is the Philips any good?

 

[wisnon]

Haven't spent much time with it. Just checked that it worked and it seemed similar to AD1n. Spent more time with a TRP demo with EL51. Very nice! Also playing with vinyl.

I suppose it could be that simple. Lampizator does have some variability in the way they present things. A change in the engine would be notable however. Or maybe the buyer requested something unique that couldn’t be called the same thing?

I did not request anything different. I have asked Fred @LampiNA but he hasn’t responded yet.

 

[Tuckia]

Probably a labeling anomaly then. Please report if something new.
The rest of my PAC’s back plate looks like yours, labeled for PX25/101D.

Today I am going to listen with a pair of Tak 300Bs and an Acme 274B. All 3 tubes are well broken in.

Would love to see what you think of the taka 300b.

 

[sbnx]

Everyone talks about the Tak 300B's. I got a pair of EAT 300B's and they sound fantastic. Basically the same price point as the Tak's.

 

[Golum]

Would love to see what you think of the taka 300b.

And i like that we sit and enjoy RDs

I really liked them in my Big 7 MKII.

I guess I am still one simple dude as for me the standard KR242 lights up my ears
