Newly Built 5F2a, Low and Bad Sound...

[PFCnR]

"What do you mean by "mechanically sound" ?" a good sturdy ground connection, check grounded terminals on pots & components with an ohmeter, to main chassis ground. Should read lowest, default setting on the meter. If any look suspect, reheat/resolder, crimping/staking the wire/component to it's location.

Here are the pictures.

And the values of ohmmeter is below 1. It shows 0.8 ~ 0.9 is it good?

The parts on the board don't line up any better with the socket pins that they feed, than they did before. You still have way too much wire in that amp. Grid wires are not shielded. That wire from coupling cap at V1 pin 6, to 6V6 pin 5 is way too long & badly routed.

Until the wiring & layout issues are dealt with I can't offer any further advice.

Hello MWJB, I found the problem and fixed it last night but i still can not believe that!! The problem was not the amp but the guitar cable!!!! How stupid am i? I just wanted to be sure that everything is fine till i post a message here The amp was very quiet when i did not plug my guitar cable in and i got suspicious about that and when i open the jack it was all broken and rusty!! I was like what the..! Then i tried another cable and amp was singing as hell!! AMAZING!! Great sound and LOUD! Now i know and believe when people told me that 5w Tube amp is loud for apartment using Today i learned why However if i look on the bright side, i have learned a lot while i was messing with the amp. I still can not believe that it was the guitar cable!

Next step is, what kind of cabinets would be good for my Jensen Mod 8". Do you guys suggest me any good type of wood to make its sound even better!!

Thank you all for being so patient with me and spending your valuable time to me! I have learned my lesson, check the cable first!

Glad you managed to sort it out. You wouldn't be the first to make the mistake thinking it the amp was the problem when it is a bad guitar cable.
