6.3VAC to 6.3VDC LDO supplies MIC5156 based tube amp upgrade.

[v4lve lover]

I made a batch of MIC5156 based LDO supplies, parts cost is 15 euro selling these for €27.50 for my troubles in assembly and testing, ex shipping. Will ship worldwide at cost.

I have 6 available that arent spoken for, Reichelt will deliver the coolers sometime this week, and then its an afternoon of soldering to get them ready to ship.

Photo attached of my previous batch.

Fully tested and assembled, €27.50 or about 30USD.

Boards are good for 2.5A provided the winding can deliver that much current as the 2x 15mF 10VDC has quite an ugly current waveform.

Once these run out, i will do another batch either as a parts kit or assembled of Revision 2. its the same board but more through hole components.

Reichelt delivered the coolers, and i have allready shipped and tested two, 4 remaining

Sale pending on last two modules.

For all those who have missed out, I am leaving the gerber files in this post. So you could theoretically build your own units.

Be aware that the main filter capacitors are 22.5mm snap-in types, not 25mm. And these are quite hard to source. Mouser-nr. 871-B41231A3159M000
Fet: 512-RFP12N10L
Controller: 998-MIC5156YN
Cooler is a SK129-38 available from TME or Reichelt.

I will be making another batch of 4 units in the next two weeks.

I will have to hike the price to €32.50 each due to more expensive components and smaller series size.

 

[v4lve lover]

Two of the next batch remaining.
