TOA - converting private keys from Electrum TOA wallet p2pkh to more often used

[PVkFrKxY9dcIswppl5xa]

Hi,

there is no more a connection to the Electrum TOA servers, where I created my wallet and saved my coins :-(

Therefore I tried to transfer the coins to another wallet, but it didn't work with the p2pkh private key (starting with a '9').

Is there any possibility to transfer the private key into another more often used format, e. g. Private Key WIF Compressed, 52 characters base58, starts with a 'K' or 'L .

Or is there any other possibility to get access to my coins

Thank you, George
