Fuse to use in an old VHT Valvulator 1?

I read that many of the older VHT Valvulator 1’s owners, had issues with the 1/4 fuses blowing out.
Both are under the protection of a Monster 250 Power Conditioner’s high powered plug in socket.

Can I switch out the 1/4 fuse for 1/2 fuse ?

And where is th housing of the fuse located at ?

Yes, it is preferable to switch to the 1/2A internal fuse.

Here is a photo showing its location.

May be I should just send it into Freyette for the modification.
It is way too cramped for me to do it on my own.
Thanks for answering my question.
That fuse needs to be soldered in ?
It doesn’t look like something that can be pulled .

Depends on the age of the unit. Older models do not have a socketed fuse.
At any rate, you’re welcome to send it here for servicing.

Send your full name, address and unit serial number to support@fryette.com and we’ll reply with a return authorization and shipping instructions.

Cheers,
