Hi ,

I am interested too on this. In fact I bought your I tube Zator 2 years ago when I was in Nz, populated and waiting for a dac to mount it. I always remember you are a helpful guy. I can see the RB is damn good and sexy, great one!

A fast few Question, I want the 1541ax1 runs passive,nos, simple psu. Do I still need the shunt board and psu board? Sorry I am not good in digital stuff.

PM me please... tq.

Default Are these boards still for sale?

Hi there
Does anyone know if the red baron and tubeizator are still for sale?
I want to set up an sd card reader that outputs I2S into the red baron and then a tube output.
What boards will I need?
The other option is to have a seperate dac like the buffalo so I can decode higher res files I make from recording my vinyl. I use an maudio card to record 24 bit 96kHz for vinyl so I figure i will need 1. SD card reader 2. dac with i2s (one being tda 1541A for cd resolution and another for hi res) then the tube output stage.
Thanks

Hi,

the Red Baron and the Tube-I-zator are in stock.

For the Tube-I-zator you will need only a transformer, because the PSU for HV and Heater is on board.
The Red Baron needs four regulated input voltages (-15V, -5V, +5V and +3.3V).

Best regards,
Oliver

Default Hi Oliver

Thank you for your reply.
Could you pm me prices for boards including shipping to Australia. I was thinking about 2 sets of boards.Do you sell the regulated dc boards as well?
regards
Nick

Any good TDA1541A DAC kit?

The minimum orderable quantity from Laptech is 5 pcs for each frequency.
When that quantity will be reached I ask Laptech for a quote.

As promised, the list of interest is started.

Hi Oliver,

Long time! My DAC is mothballed at the moment....the old Teradak USB to i2s converter is dead, it seems (It never worked reliably for me anyway). I know that people here have moved on from that device. What are the best options these days for various inputs please?

Many thanks
Lucas

- Will use ipx mini coax cables to connect spdif module to PCM board
- PCM and DAC boards will be hard soldered, 2-3cm cables will go directly to TDA chip.
So I made the updates and burned one reg on PCM board accidentally! Anyway it's fixed now!
Sorry, no pics, will provide later.

A question most likely to Oliver
As a result of my update, I do not get any sound from the TDA chip now (w/o DDNF board). It is set to simultaneous mode as it should for PCM daughter board. All connections are triple checked and are the same as before I added mini coax cables and the DAC was working. The schematics is triple checked as well and is equal to v5.0.
When scope is connected, all 4 outputs (Data L, Data R, BCK, LE) have proper signals. Ian has confirmed that PCM board should be fine, but the output from TDA is completely silent. The only thing that could be is the DAC board I assume.

Unfortunately the worst thing here is that I'm stuck with this issues already for a month Would very appreciate any help!

Default My Red Baron 5 is also still not working

Well I still have the problem stated further back. No sound either. I'm not using Ian's boards however I have tried the version 5 boards with waveio, aminero, exa with no sound at all. Changed tda1541a chips 3 times, used various output stages, changed caps on the dac chip. Still silence, I do get garbled noise if I change the jumper next to the chip to simultaneously mode.
Really frustrated as I have checked all components numerous times.

Anyone able to help?

that's weird as I did manage to get the DAC working with Amanero (i2s) fine and later with Ian's PCM daughter board.
Then I made the above upgrades and vuala - no sound at all...
