G4BAO boards and transistors pack

Post by g7ntg » Thu Jun 25, 2020 6:59 pm

I have secured a quantity of UK old stock transistors MRF5S9070MR1 and have ordered 60 PCB's to go with them to the G4BAO design .
the transistors give 75-80 watts ouiput saturated and 65-70 watts P1dB for 28 volts at 5 amps
I will be selling a mini kit with PCB, transistor and 5 of the ATC and C0G capacitors which are difficult to buy singly
The semi - kit will sell for £30.00 + postage,
I am waiting for PCB's and expecting them in 10 days when I will be able to start shipping.

Here is where to find information;
DATVPA@groups.io look in Files/G4BAO poweramp 23cm files
And also look in G4BAO posts
Or ,look at;
Github.com/g4bao/23cm-45W-PA

I prefer to use a 3mm heat spreader.

If you are interested don't reply here but email me at thebigclunk@virginmedia.com
