I am afraid the first batch of PCB/transistor/ATC partial kits is now sold out for the 70 watt version.

There may be one or two people drop out of the pre orders – if so the next on the new list will be contacted

I have just purchased a batch of SRF9060 transistors which give slightly less power and need a different heat spreader arrangement.

The rest of the information is similar.

G7NTG updated G4BAO amplifier for 23 cms now 60 watts

Here is where to find information;

[email protected] this site is read only and has all the information I have plus some articles on construction.

[email protected]? look in Files/G4BAO poweramp 23cm files

And also look in G4BAO posts there are member discussions here where people post ideas and suggestions.

Or ,look at;

Github.com/g4bao/23cm-45W-PA

Please do not contact John G4BAO at his request but contact me with any queries

Look on his website for a 2.5 watt driver amp although this is not enough to drive the 70 watt amp to full power.

If you want you can go on the new list and I will be in touch when I have all the parts and am ready to ship sometime in late July 2020.
