You'll have to improvise a little.

Its a fairly simple diagram and it is not strictly
important where certain component goes on the PCB, but make
sure you stick to the diagram.

Think of it as a breadboard for RF amps. Handy to keep around
for testing RF amps and transistors.

Thanks for the reply.

Do you have a component list? I dont understand what components
are used... whats 4/20p??? or 10p??? 270 4/2W???

A component list would really help.

Thanks.

If you don't know that 10p means 10pF you obviously
don't have much experience, if any.

4/20 is a trimmer, 4-20pF.

If 10p means 10pF then why not put 10pf on the diagram? I have quite a bit of experience in building circuits as i can read and follow instructions.

The digram on the site only gives very vague idea.

However, bearing in mind what you have said i will have a go at building the amp and let you know what happens.

Thanks for the reply

BTW 10p = £0.10 where i come from

Let me know if you have any more problems.

I think we're clear for now, no?

Have fun!
