Thunder 1 capacitors

[cgmaster]

I was wondering if any had a list of all the capacitors in a thunder 1 amp thanks

Welcome to LTG! There are two versions of that amp. The early one is cathode-biased and the later one is fixed-bias. You can find a schematic for the latter here: http://www.prowessamplifiers.com/schematics/images/Guild_Thunder_1_12.pdf
There's no parts list, but you can at least go through it and make your own list and check it against the values you find in your amp. It's tedious, but that's all I got.

Filter caps or caps in general?

All the capacitors that are in the amp please

Thanks I was going to do this I just thought someone already had a list to make it a little easier

No, Guild amps aren't available as diy kits, like Fenders or Marshalls, so there aren't any build lists that I have ever seen. Also, there might be running changes that might not be in the schematic.

Thanks I have a question,I’m pretty new to tube amplifiers so excuse me if I ask stupid questions but if the later is fixed bias on the 6GW8 power tubes where is the grid for the pentode side of the 6GW8 getting it’s negative D/C voltage from and why does the pentode side show only four elements in the diagram also the first capacitor in the Schematic is not to clear as to the value of its capacitance it looks to me like .01 microfarads but it is blurry in the schematic diagram

It's a cathode biased amp. No negative to the grid. Are you working on a Thunder 1 or a Thunder 1 RVT?

A thunder 1 1966 it was my uncles amp he passed away at 83 so I want to restore it in his memory any help would be greatly appreciated thanks

Does it work? Best to find out what it needs first, rather than make up a list of parts. Filter capacitors need to be replaced, most likely.

Have you ever worked on an amp before? Tube amps can kill you dead.

why does the pentode side show only four elements in the diagram

The answer is here: https://www.tubesandmore.com/sites/default/files/associated_files/6gw8.pdf

I wound not trust the schematics too much, as said there were many variations. So best is to check the actual cap present in the amp for it's value printed on it.

And... this.

I am a master electrician with 32 years experience I have worked with 13200 volts A/C so I know all the safety protocols and precautions sir but thanks for your concern Good day to you sir!

Generally, an experienced tech does not ask for a list of capacitors for a particular build. They see what the amp needs, and just fix what needs to be fixed.

Sorry I was asking for information I don’t know everything like you guys my mistake
