sunn amplifier guitar amp

Description

This is a 1970 Sunn 1200 S guitar amp in full working order it has be serviced recently and is in full working order the amp does not to be fixed and works without any issues.
It has 6550 tubes and a rectifier tube.
There is a tag it said it was tested 9-2-70.
This was only serviced one time and was still all original still has the original transformers.
The original reverb tank had to be replaced with a newer one.
The front grill cloth has damage to it you can see in the photos and it doesn't have any sunn logo.
The amp has a of volume I don't think it has a gain.
I don't know how well the tremolo works or how good it is but the reverb and the tremolo effect both work.
The boost switch works too but when you turn switch on you can hear some more noise come from the amp when its on and when its not being played.
It is a loud amplifier I have not used it passed volume two or three and only been used lightly since the 6550 tubes were bought for this amp.
It has an 8 ohm speaker output.
All the four front inputs work and all the controls work.
This is a real heavy amp i'm not sure how much it weighs.
The amp is not being used but its a good working amp that's the reason it is for sale.
The amp is sitting on a 4x12 cabinet but that is for sale in another listing this was just for the amplifier.
Please ask if there is any questions about this item.
Thank you for looking.
