Build Thread for TPA BIII + Ian Async I2S FIFO + OPC NTD1 + Salas SSLV - Page 2

Hi qusp

Hope you understand that English is our second language and sometimes we misunderstand your meaning.

I understand that perfectly well, but sorry there is no way that can be used as an excuse for this. I posted it long ago, then posted that I may be able to find a few but was not making a commitment and was certainly not offering to do it for the whole group due to the time involved, I went to great lengths to explain it and what a nightmare it was last time.

then another few people added their name with fets, I clarified again that I wasnt offering them to the group but with the possibility of a just a few.... again, then more people added their orders (some native english speakers) then hochopeper stepped in to mention I wasnt offering them, then straight after his post 2 people edited the list to add fets to their orders and another person added a new order with fets, I laughed about it with opc in the thread, agreed and confirmed that hochopeper was correct, another one or 2 made orders for PCB plus fets and just now another person added an order for PCB + fets.

I dont know what else I can possibly do and its not just this GB, the wire headamp and power amp threads were the same, english or not, it doesnt matter people still post asking for PCBs to this day

Haha, my English cause you misunderstand my meaning. I meant I didn't know OPC has confirmed the GB. I share your feeling on the fet. Sorry that I am one of the guy edit the list to add fet.

hochopeper · 17th May 2012, 01:51 PM

FWIW, my trick to navigating any thread where PCBs are available or GBs are going on I generally click 'search this thread' at top of the page for the thread then advanced search and search for posts by the GB organiser by only populating the username field then clicking search so it finds every post by the GB organiser.

This method tends to avoid misinformation and confusion and gets the information I'm most interested in (what the GB organiser is saying is the single source of truth).

Thanks again, this really help.

.

If I read every post carefully, I can save $150 for the legato. May be sell it at Swap Meet!!

hochopeper · 17th May 2012, 02:03 PM

All good, I find some of the GB threads tend to have everyone circling like a pack of sharks wanting to get their hands on whatever is possible and it can quickly get out of hand and good information buried deep in a thread. Which is why I think its almost impossible to follow without tricks like using the search!

For calculations on the salas regs have you tried the spreadsheet attached to this post? I have found it quite handy and makes heatsink considerations a bit simpler also!

Yes, I am using the spreadsheet to calculate the resistors.

I won't build the 15V SSLV for the legato and will concentrate on sourcing components for the NTD1. THanks again for your advice and help.

bigpandahk · 19th May 2012, 02:55 PM

Yesterday, ordered most of the components from Digikey. Now counting the transformers, two AN0540 + one AN0006 for the NTD1, I had the 12V 50VA for the BIII. May be another 6V for charging battery for FIFO.

Please tell me if I miss anything else. While waiting for the PCB + FET and BIII, will try to figure out the size of heat sinks. Won't consider the chassis unit everything get connected.

bigpandahk · 20th May 2012, 12:34 PM

While trying to get some idea on the heat dissipation of the NTD1, I search OPC's build thread and found that I don't need the AN0006 transformer because I am not using the B1. Fortunately, I haven't ordered it yet. It is really a hard job to go through hundreds pages of post with new development everyday and have to ensure won't miss any important issue:-(
